Python Tip #181 (of 365):

Don't use Python's "str.title()" method.

It capitalizes letters after apostrophes, turning "don't" into "Don'T".

Here's the problem:

>>> "Python is a don't-miss language".title()
"Python Is A Don'T-Miss Language"

str.title() defines a "word" as anything following a non-letter character.
Since ' isn't a letter, the t in "don't" gets capitalized.

For most cases, capwords() from the string module is a better choice.

Python Tip #180 (of 365):

Zero-pad numbers with f-strings.

Need to format a time like "9:05" instead of "9:5"?

Use "02d" in your f-string format spec.

Without zero-padding:

>>> hour, minute = 9, 5
>>> f"{hour}:{minute}"
'9:5'

With zero-padding on the minutes:

>>> f"{hour}:{minute:02d}"
'9:05'

The "02d" format spec pads the number with zeros until it's 2 digits long. 0 means "zero pad", 2 is the minimum width, and "d" means integer.

uv 0.11.25 is a small but useful security release: it bumps its internal tar library, astral-tokio-tar, to v0.6.3, which tightens how source distributions are parsed. uv may now reject sdists with malformed or ambiguous content it previously accepted without complaint.

Python Tip #179 (of 365):

Use history & paste mode in the new REPL. 🧵

F2 enters history: previous code is shown WITHOUT >>> prompts, so you can copy just the code.

F3 enters paste mode: Enter won't accidentally run your code block while you're editing it.

I find history mode (F2) useful for copying code out of the REPL.

In history mode, you see just the code you typed, without the prompts and output intermixed.

Python Tip #178 (of 365):

Hack your Python REPL.

The REPL in Python 3.14 includes syntax highlighting. It's pretty great!

But did you know that you can customize the color scheme it uses?

You can also customize other REPL features, like adding your own custom keyboard shortcuts.

#EP2026 #TooManyHashtags #SorryNotSorry

Python Tip #177 (of 365):

Learn your REPL's keyboard shortcuts. 🧵

This is especially useful in Python 3.13+ because there are even more useful shortcuts.

The most useful: Ctrl+P and Ctrl+N navigate between blocks (not lines).

There's also:

• Ctrl+L: clear screen
• Ctrl+R: search your history
• Alt+Enter: run current block
• Ctrl+K: delete from cursor to end of line
• Ctrl+Left / Ctrl+Right: jump one word at a time

Leveraging Python 3.13+'s improved repl to show a preview of what my RPN calculator will calculate ...

_1k switches the calculator into a mode where it shows fractions as repeating decimals.

It's RPN so in the end, (1 - 2/3) is shown as the repeated decimal 0.3 with a bar over the 3.

I updated my blog post about using pyrepl in your own programs: https://emergent.unpythonic.net/01781963135

#Python question:

So I can do this to increment some value:

```
a += 1
```

And I can do this do make a value roll through `0, 1, 2, 0, 1, 2`:

```
a = (a + 1) % 3
```

Is there some shorthand which combines these two?

Python Tip #176 (of 365):

Customize your REPL with PYTHONSTARTUP. 🧵

If you set the PYTHONSTARTUP environment variable to point to a file containing Python code:

export PYTHONSTARTUP=~/.pythonstartup.py

Python will run that file at the start of each new Python REPL.

For example, ~/.pythonstartup.py might contain:

from pprint import pp
from pathlib import Path

Now those are available in each new REPL:

>>> Path.cwd()
PosixPath('/home/trey')

Since it remains unclear whether my current #PostDoc contract will be prolonged in January, I am starting to look for a new #AcademicJob!

My expertise are #ecology, #ethology, #AnimalBehavior, with a focus on #olfaction in #mammals.
I had a stint in #NeuroEthology, but that wasn't quite my cup of tea, and I am currently working in #AnimalWelfare for husbandry animals (think cows, pigs etc).
I have done field work (wild rodents), lab work (very controlled behavioral assays), and pure data analysis.
I do everything in #rstats, so my standard analysis tools are GLM/GLMM, but I'm currently learning how to properly use Generalized Additive Models, as they seem like the natural next step.
I've also dabbled in #python in order to work with #DeepLabCut and #moseq, so the last few years I spent mostly with #ComputerVision, #DeepLearning, and extracting data from videos.
As that requires heavy GPU calculations, I've done most on my work on institutional and/or national #HPC, and then crunched the masses of resulting data in #rstats

I'm looking for a job in the #EU, preferably anywhere north of Germany, but let's be honest, I'll go wherever there is a job.

Python Tip #175 (of 365):

Pass "-i" to #Python to drop into a REPL after your script runs.

$ python -i fibonacci.‍py
>>> nth_fibonacci(10)
55

You'll have access to everything the script defined.

Passing "-i" is like pasting your script into a REPL.

After the script runs, you're dropped into an interactive session with all variables still in scope, even if the script crashed.

It's handy for debugging: run your script, inspect what's in scope, and figure out what went wrong.

I've spent years maintaining the UNICORN Binance Suite, dealing with those weird edge cases where WebSockets look alive but are actually dead to your trading strategy.

Since most tutorials completely skip these production-level failure modes, I wrote a comprehensive Python API guide for 2026. It focuses purely on data integrity, proper lifecycle handling, and local depth caches.

If you are building crypto trading tools with Python, I hope this architecture blueprint saves you some sleepless nights.

Python Tip #174 (of 365):

Python modules are cached.

The first time each Python process imports a module, it caches it in sys.modules.

The second time you import the same module, Python returns the cached module object without re-running the module code.

This means if you edit a file and then re-import it in the same REPL session, your changes won't appear.

Re-importing a module does not reload it.

The simplest fix: RESTART PYTHON.

Python Tip #173 (of 365):

Use _ to see the previous REPL result.

Say you ran an expression in the REPL and only decided AFTER you ran it that you want to capture the result:

>>> 2**50
1125899906842624

This is what the REPL's magical _ variable is for.

The last result the REPL generated is stored in the _ variable.

So you can just point a different variable to that value:

>>> n = _
>>> n
1125899906842624

This week's tips are all about the Python REPL.

Python Tip #172 (of 365):

Know your object introspection tools

When you're in an interactive Python environment remember that these 4 tools can be helpful for introspecting the state of your Python process:

1. type
2. help
3. dir
4. vars

type shows the class of an object (the terms "class" and "type" are synonyms in Python).

If you have a mystery object, type can tell you what it is:

>>> type(letter_counts)
<class 'collections.Counter'>

I blogged what I've learned about using the _pyrepl module in Python 3.14+ to add multiline & colorized input to my own project. https://emergent.unpythonic.net/01781963135

Customize PDB with a ~/.pdbrc file.

You can make a ~/.pdbrc file to add your own commands to the Python debugger.

This ISN'T a Python file, so it's a bit tricky to create, but spending a few minutes making one is well worth it.

At startup, PDB runs commands from a ~/.pdbrc file.

The handiest thing to put there are custom PDB aliases.

An #introduction perhaps?

I’m this middle-aged dad from Germany. I have a wonderful partner, 4 kids and a cat.

I care about society and technology. A retired #FOSS activist, these days I work at a globocorp doing IT stuff for trains 🚄

My interests include baking #bread, #fermenting stuff, paddling a whitewater #kayak, n00bing around with #Python, #RaspberryPi and #arduino, and oh so many books.

There’s never enough time, and I haven’t been bored in more than a decade.

Python Tip #170 (of 365):

Use b to set a breakpoint while you're in PDB

You can use the b command to set a breakpoint at a certain line of code:

(Pdb) b 4
Breakpoint 1 at script.py:4

But why...?

Why not just add another breakpoint() call?

Well, imagine you've entered PDB via post-mortem debugging (see tip 154 from yesterday).

You've realized once you're IN PDB that it would be useful to pause on a particular line.

The b command makes that easy!

Python Tip #169 (of 365):

Use PDB's post-mortem mode to debug exceptions

Python script raising an exception and want to drop into an interactive environment RIGHT after the exception occurs?

Use "python -m pdb your_script.py"

Using "-m" runs the pdb module as a script.

When launched like this, PDB enters "post-mortem debugging" mode.

You'll drop into PDB as soon as your program launches.

Python Tip #168 (of 365):

Want to start a proper Python REPL within PDB?

Run the interact command:

(Pdb) interact
*pdb interact start*
>>>

Before Python 3.13 added support for multi-line Python expressions within PDB, I used interact often.

Launching a Python REPL was essential whenever I needed to run a block of code or even to span one line over multiple lines with code wrapped in braces/brackets/parentheses (thanks to implicit line continuation).

Python Tip #167 (of 365):

In PDB, prepending a line with ! will force it to be treated as Python code.

This is especially handy when your expression starts with something that PDB thinks is a debugger command.

For example, n is a PDB command ("next line"), so if you have a variable named n, typing this won't show its value:

(Pdb) n

Instead, use "!n":

(Pdb) !n
'1'

The ! tells PDB to treat n as Python code, not as a PDB command.

Python Tip #166 (of 365):

Consider using PDB to debug your code.

Instead of temporary print calls, consider using Python's breakpoint() function to pause your program and drop you into the Python debugger (PDB).

Here's a tiny example:

from random import randint

breakpoint()

answer = randint(0, 1)
n = input("Guess: 0 or 1? ")

I'm looking for work, please boost!

I'm a senior software engineer with 35 years of experience. I've worked across an unusually wide range of domains: mobile game backends, privacy-preserving data platforms, high-throughput COVID testing infrastructure, email and account systems, e-payment processing, job marketplace systems, and bioinformatics. I pick up new domains quickly and have a track record of doing it repeatedly. I understand how to turn business needs into engineering requirements.

I've worked remotely since the 1990s and can operate with minimal supervision. I don't need hand-holding to find the right problem to solve. Several of my most valued projects were self-directed: I identified the need, built the thing, and shipped it.

Some of the technologies I'm familiar with include: Python, Perl, TypeScript/JavaScript, Haskell, Go, C, Java. Postgres, MySQL, SQLite. Flask, SQLAlchemy. AWS (Lambda, S3, RDS, SQS, EC2). Docker, Git. Github and Gitlab.

I've also repeatedly picked up new languages and stacks as needed: Haskell for differential privacy research, TypeScript for a 24/7 AWS Lambda system, Flask for my most recent employer. I've become productive with new systems over and over, and I can do it quickly.

I'm also a published author (Higher-Order Perl, Morgan Kaufmann), longtime blogger, and conference speaker with a reputation for making complex ideas clear.

@JallBarret Hardcoding the path like that would break execution of the script in a virtual environment (which is exceedingly common these days), so I wouldn't do that. A better shebang line would be `#!/usr/bin/env python3`, since that will resolve it using PATH, and I believe /usr/bin/env is very standard on POSIX-ish systems.

Python Tip #165 (of 365):

You can make a set of sets by using frozenset.

Sets can only contain hashable objects. And regular sets are NOT hashable:

>>> groups = {{"a", "b"}, {"c", "d"}}
Traceback (most recent call last):
...
TypeError: unhashable type: 'set'

So you can't make a set-of-sets with regular sets.

>>> b = {1, 3, 5, 7, 9}
>>> a | b
{1, 2, 3, 4, 5, 7, 9}

Welcome to #linux! It's super easy! To install packages, just use the GUI... oh. Oh that one. Well, that is super easy too! Just open a terminal and type pip3 .... oh, that? Yeah, you just have to figure out what a virtual environment is, figure out how to create one, whether to create a new one every time, how to manage it, and how to install your software using that! Oh you'll need some other libraries for that, and maybe to install some new things in the venv and oh yeah that's a common problem. It just means you have to... where are you going? It's super easy!

pipx seems like a good alternative except apparently it can't install what I need, for some reason. Back to trying to figure out how to set up and use virtual environments so I can install a damn thing.

Edit: It's not actually hard to do this, unless there are complications. It's just yet another damn thing to remember, and more steps to go through. Hoping this #pipx tool gets developed enough that it can do all of this with one command.

Edit 2: So I'm not That Asshole: what I did, from here
https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/

python3 -m venv .venv

Python Tip #160 (of 365):

Using list.insert(0, ...) in Python? Consider using a deque instead.

Inserting at the beginning of a list is slow because every existing item needs to be shuffled over.

On my machine, this takes multiple seconds to run:

numbers = []
for n in range(200_000):
numbers.insert(0, n)

There's a better structure than a list for this situation...

Python Tip #159 (of 365):

When it comes to modifications, think of lists as stack-like.

This week's tips are all about lists and data structures.

Regardless of how large your list is, these are both very fast operations:

items.append("more")

last = items.pop()

Lists are optimized for adding items to the end and removing items from the end.

gh-profiiler's bulk processing feature is a really interesting way to see how AI has been affecting contribution patterns in different projects.

Here's the 25 most recent merged/closed PRs in cPython. Most were merged. Two of the three PRs that were rejected were submitted by a user who raised a red flag when profiled.

To be clear, cPython maintainers are not using gh-profiler to make these decisions. But the output is aligning reasonably well with those decisions so far.

#Python #OpenSource

Alt...

Output of `uvx gh-profiler https://github.com/python/cpython -n 25 --back --table-only --redact`. It shows 22/25 recent PRs merged. There are two user profiles with red flags, and both of those were users whose PRs were ultimately closed without merging.

Released yesterday, but only got to publish the blogpost and push to pypi today: happy to announce the version 1.16 of slixmpp, the #python #xmpp library.

Python Tip #158 (of 365):

If you had to choose, prefer automated tests over type annotations.

Of course... you don't need to choose. You can have both!

A type checker can tell you that your function returns the wrong type but it can't tell you that it returns the wrong answer.

Type annotations catch a specific category of bug: passing the wrong KIND of object.

Tests can catch that and more: logic bugs, incorrect output, mishandled edge cases, etc.

Weekend project that turned into infra I actually run daily: MastoSum.

The stack: RHEL host, 100% rootless Podman. Web on FastAPI, Celery worker/beat/flower, PostgreSQL 16, Valkey. All on userspace networking (pasta), images built & shipped by a self-hosted Forgejo runner. No root daemon, no privileged anything.

What it does: tracks technical hashtags all day and produces one daily briefing, every point linked to the original post + author. It reads only public hashtag timelines, credits every source, and trains on nothing.

And yes, an LLM writes the prose: a local Ministral model from French lab Mistral AI, running on my own hardware. No cloud, nothing leaving the box. Saying that plainly, not burying it. The whole design goal was to point readers *back* at the authors, not replace reading them.

Python Tip #156 (of 365):

Parsing JSON with json.loads hands you a blob of nested dicts and lists with no structure.

But you CAN describe the shape, so a type checker (or pydantic) can catch typos and wrong assumptions.

Parsed JSON has no schema. Nothing would catch a mistyped keys:

>>> import json
>>> book = json.loads(response)
>>> book["titel"] # typo, no warning

You only find out at runtime, with a KeyError (if lucky) or a subtle bug (if not).

Could it be a matter of "just" adding a constant so they more or less match? Or could it be related to mixer volumes and different mics (phone vs computer)?

Python Tip #155 (of 365):

When a method returns an instance of its own class, annotate the return type as Self.

Hard-coded class names break for subclasses:

class Connection:
def __enter__(self) -> "Connection":
self.connect()
return self

If PooledConnection inherits from Connection, a type checker will think PooledConnection().__enter__() returns a Connection (not a PooledConnection).

Python Tip #154 (of 365):

Writing a type that's "this or that"? Use the | operator instead of Union or Optional.

"int | str" reads better than "Union[int, str]", and "int | None" reads better than "Optional[int]".

The old way involved helpers imported from typing:

from typing import Optional, Union

def parse(value: str) -> Optional[int]: ...

def normalize(value: Union[int, str]) -> str: ...

Python Tip #153 (of 365):

When you write type annotations, embrace duck typing: annotate with the most general type you can.

Don't require a list if any iterable will do. Don't require a dict if any mapping will do.

Most functions that "accept a list" actually accept any iterable.

Instead of:

def square_all(numbers: list[float]) -> list[float]: ...

Prefer:

from collections.‍abc import Iterable
def square_all(numbers: Iterable[float]) -> list[float]: ...

#Python

Python Tip #152 (of 365):

Be consistent about your type annotations: skip them entirely or run a type checker.

An unchecked annotation is really just a comment, and it may be a confusingly incorrect comment. A type checker keeps your annotations honest.

Annotations can add noise to code, but they can also increase correctness.

Half-annotated code that isn't type checked adds visual noise WITHOUT adding the safety of type checking.

For truly unpredictable randomness, use the secrets module

Python's random module relies on pseudo-randomness, meaning it generates numbers in a predictable order. If someone can guess the random "seed" (it's based on the current time) they can predict the numbers produced.

For true randomness, use Python's secrets module instead.

@pycon @BajoranEngineer @djangoconeurope Dawn’s keynote was a great way to close the second day of PyCon Italia 2026.

The talk sparked lots of questions from the audience, and the discussion could probably have continued much longer.

To wrap up the session, we took a final selfie together on stage before bringing the second day of the conference to a close.

Python Tip #149 (of 365):

Sort by specific attributes with operator.attrgetter.

Have an iterable of dataclasses, namedtuples, or some other record-like object?

Want to sort them by a specific attribute?

Use operator.attrgetter:

from operator import attrgetter

For example, if we had an iterable of Book objects that have a title attribute, we could sort them by that:

sorted_books = sorted(books, key=attrgetter("title"))

Closing the second day of @pycon 2026 as talk manager for @BajoranEngineer keynote.

After a long day, I’m tired but genuinely happy to help Dawn on stage. Years ago, she helped me when I gave my first talk abroad at @djangoconeurope 2019 in Copenhagen. It feels special to return the favour.

Her keynote, "Stop Being a Generalist", explores why going deep on a domain can be more valuable than trying to do everything.
