Das Leben beginnt erst richtig mit 80…
Eines der größten Mankos des Commodore C64 ist die Anzeige von nur 40 Zeichen pro Zeile. Darunter litten vor allem Textverarbeitungsprogramme. Doch mit entsprechenden Erweiterungskarten wurde schon früh Abhilfe geschaffen. Diesmal geht es um den B.I.-80 Display Adapter von Batter…

Dnes jsem poprvé použil https://docs.python.org/3/library/graphlib.html a ušetřilo mi to spoustu práce!
Vyvíjím #juniorguru a mám slovník, kde klíče jsou názvy „jobů“ a hodnoty jsou seznamy názvů jejich závislostí (jiných „jobů”). Dva řádky kódu a mám pořadí, v jakém bych to celé měl spustit, abych závislosti dodržel. Nemusel jsem instalovat networkx nebo něco, nemusel jsem si to programovat. #python #batteriesincluded
As the August reaches its end, so does Blaugust. I reached my goal of 31 posts in 31 days but it wasn't without some tough times and challenges.
With this retrospective, I wrap up this year's Blaugust and return to my regular schedule with blogging.
Thanks for everyone who's been part of this journey and who has commented, discussed, taught me new things and supported my journey.
Batteries included blog series wraps up today with a book recommendation. It's been a fun (and challenging) month to write about Python's standard library.
Tomorrow is time for reflection and retrospection but until then, here are my thoughts on Fluent Python, a great book for all Pythonistas.

Python 3.13 and 3.14 are bringing some new features like calling random from command line, calling json without json.tool and improved REPL.

Python is a great programming language with even greater community.
One part of this wonderful community are the many podcasts of which I've picked four favorites to write about.
Python's sqlite bindings make sqlite a great prototyping companion.
I don't only like using command line tools, I love writing my own too. Python's argparse is a nice built-in way to parse arguments, options and subcommands for custom CLI tools.

I use Python's interactive REPL all the time: to experiment, to build new features, to run one-off operations and to debug issues.
You can make it even more powerful if you bring your own PYTHONSTARTUP script with you to set up your environment exactly as you want.

Logging is one pillar of observability and Python's standard library has logging module to get you started.

If you're doing same long-running or memory hogging operations often, functools.cache helps you write more performant code by storing the results and accessing them from memory.
In Python, we use list comprehensions to run do map and filter operations and I love it.

zip function is one great example of why I find Python such an elegant language to use. It makes iterating over multiple iterables easy and readable.
Summer season is #handheld season! I'm picking up #californiagames surfing again. Let's see if this old man can still land his quadruples! Any fans?

Today, I continue the Batteries included series with a post about combinatoric iterators.

Today in Batteries included I take a look dataclasses in Python.

There are a lot of great #debugging tools for Python but even with just standard library with no external dependencies, you have powerful tools with the Python debugger.
Printing complex data structures becomes better when you use pprint.

Python is very good at counting things. And collections.Counter offers one great way to do that.
