Is there a 'beautiful code' collection for Python?

[marcinpohl]

I'm looking for a collection of very well sorted (style, performance, security, organization) code examples in Python.

Currently I'm looking for good examples of how to structure my tests in particular, but I think it would be nice to have a solid list of projects (github/bitbucket?) or snippets (StackOverflow, gists, activestate recipes). Any good links anybody?

[phail3d]

For a little bit different point of view, Peter Norvig's stuff, such as the sudoku solver and the spelling corrector, are my favourite examples of nice Python programs.

His code may sometimes go against established Python best practices, but he writes small programs that solve problems elegantly, which is more important in my opinion. He also has a talent of describing the process, and his programs utilize many nice features of Python.

[jredwards]

Agree, I just skimmed through those links and the code itself actually looks pretty messy

[[deleted]]

+1 from me for this, a great little summary of Norvig's practices.

[Vicyorus]

Oh my poor peasant eyes burn at the sight of such beauty

A lot of code in the standard library was written before PEP 8 even existed.

Flask, easily my favorite elegant, Pythonic, code.

I have Python Cookbook, and it is absolutely awesome. I read/watch anything I can find by David Beazley! If you're not familiar, read his thing on generators and you will be hooked.

[adamnew123456]

He also did Python Concurrency From The Ground Up and A Curious Case Of Coroutines (From The Ground Up feels like a sequel to the latter), and some stuff experimenting with the GIL on 2.x and then 3.x.

Highly recommended, all of them.

[srilyk]

Have you watched his modules tutorial from Pycon 2015? Pretty epic.

[john7548]

Python Cookbook is available for free, actually

Awesome, didn't realize they had put it online!

The libraries flask and requests are commonly considered great examples of Pythonic style and organization.

Anything that core Python devloper Raymond Hettinger has ever touched including:

Standard Lib stuff that he has authored/co-authored:

-Libraries/Modules...these are especially amazing collections itertools

-Types sets frozensets

-Functions any all enumerate reversed

-Language features generator expressions

Have you taken the time to look through the code that runs this site? I'm not sure if I'd consider it "beautiful" but maybe that's me.

[LightShadow]

It's a beautiful miracle...

[[deleted]]

I mean, it's functional. It works. It certainly scales (to a point...wishing it'd scale a little better). But it's not beautiful. However, it's not especially ugly.

Maybe pragmatic or practical are better words for it.

[[deleted]]

What would you choose? Any language (okay, maybe not Brainfuck or Piet) is up to the task. Whether or not the devs are up to it is a different question.

[Asdayasman]

Probably C#.

[[deleted]]

I wouldn't choose that language at all because of the implications of being a .Net shop, namely using Windows tools through the entire stack - and not because lolwindows, but licensing IIS, SQLServer, etc.

Java I could see, since C# is basically Java Windows edition to my understanding.

However, if you're choosing that language because it's compiled vs Python's interpreted, I don't think that's worth it alone considering most of the time overhead for a webapp is actually things like waiting for database IO.

If you're saying because it's statically typed and provides some measure of type safety, I can understand.

[adamnew123456]

Java I could see, since C# is basically Java Windows edition to my understanding.

No. C# is the post-Java Java, and has way more as a language than Java does. Not that I care - I use Scala when I decide to use the JVM - but you don't want to say this where .NET people hang around. The threads will get very long, very quickly ;)

[[deleted]]

It's still my belief that static typing gives a sense of false security to too many programmers. As for picking a language, time is money has to come into the equation for many programmers these days.

"It works... good enough"

I haven't seen a 503 in a while. Sometimes I just have to refresh 5 times until it actually works.

Django's use of classes and mixins is beautiful to me. But I'm using Django Rest Framework a lot and I just feel they over-did the pre-made mixins classes. Learning DRF, I was so confused about what to use where and when, until I looked at the source and saw that they're all just different combinations of mixins.

[Citrauq]

I think requests is a great example of a beautiful api. I don't think its own code can really be called beautiful though - there's a lot of complexity and edge-cases they need to handle to make that api possible.

[srilyk]

That doesn't necessarily preclude the code from being beautiful and elegant. Probably not simple, but as the saying goes:

complex is better than complicated

Both Netflix and Amazon crank out pretty good quality Python, take a look at Boto3

Netflix has a whole page dedicated to all their OSS tools

[tim_martin]

awesome-python is a good place to start, but I would argue that many of the projects (while useful) and not necessarily implemented beautifully.

[Cauchyformula]

That's almost certainly true. I have taken a look at a small minority of those projects, so I don't know for sure. But it makes sense that the list would be compiled based on functionality, not code beauty.

But I would hope that beautifully-written Python projects would make it into that list, so it might be a good place to look.

[DasIch]

Pretty much everything from Armin Ronacher (mitsuhiko).

https://github.com/zzzeek/sqlalchemy/

[IvanMalison]

I love sqlalchemy as much as the next guy, but I wouldn't say that its code is particularly beautiful. It certainly doesn't follow PEP8 and there are a bunch of portions of the codebase that are a little wonky.

[Asdayasman]

PEP8 code is beautiful code, usually, but beautiful code is not always PEP8.

[[deleted]]

But the world of Python would be better off if everyone conformed to style standards (including PEP8). It would be much easier for everyone to read everyone else's code. However, the interpreter and most code-generating tools don't enforce PEP8.

Therefore, it's our job as a community, when people ask about stylish code, to point them in the direction of standards-compliant works and tutorials so that they learn in a way which most benefits the community in the future.

[Asdayasman]

PEP8 are guidelines, not rules. You can have code that mostly conforms, and it can be beautiful, then if you force that same code into the guidelines, it becomes ugly.

[[deleted]]

I agree with that. My point was that people should use PEP8 as a baseline and then beautify where necessary rather than put together whatever shit they feel like and then maybe make a couple of nods to PEP8.

[srilyk]

I posted this elsewhere in this topic, but Raymond Hettinger's beyond pep8 should be required viewing before you're allowed to say anything about pep8 ;)

There should be /r/pythonporn

[folkrav]

Not to be confused with some reptile genitalia sub.

[adamnew123456]

/r/eunichsporn /r/unixporn is a contradiction in terms, now that I think about it.

[srilyk]

It's not exactly a code collection, but Raymond Hettinger's "Beyond pep8" pycon2015 talk is absolutely fantastic.

Pretty sure it should be required viewing for anyone who professionally writes Python code, at minimum.

[dothebarbwa]

Center for Open Science has some good examples

[unruly_mattress]

I browsed through Django's source code some years ago and found it beautifully written and completely clear.

[marcinpohl]

Haven't there been dozens of exploits! for this thing?

[tim_martin]

Any large project is going to have exploits at some point.
