stdlib-list 0.0.2

Listing the modules in the standard library? Wait, why on Earth would you care about that?!

Because knowing whether or not a module is part of the standard library will come in handy in a project of mine. And I’m not the only one who would find this useful. Or, the TL;DR answer is that it’s handy in situations when you’re analyzing Python code and would like to find module dependencies.

After googling for a way to generate a list of Python standard libraries (and looking through the answers to the previously-linked Stack Overflow question), I decided that I didn’t like the existing solutions.

So, I decided to brute force it a bit, by putting together a scraper for the TOC of the standard library page of the official Python docs (eg here is the page for Python 2.7).

Usage

The only argument you need to worry about specifying is a (major and minor) version number:

>>> from stdlib_list import short_versions
>>> short_versions
['2.6', '2.7', '3.2', '3.3', '3.4']

Or, if you prefer, an exact version of one of the standard library pages that I scraped:

>>> from stdlib_list import long_versions
>>> long_versions
['2.6.9', '2.7.9', '3.2.6', '3.3.6', '3.4.3']

With that in mind, here’s how you can grab a list of standard libraries:

>>> from stdlib_list import stdlib_list
>>> libraries = stdlib_list("2.7")
>>> libraries[:10]
['AL', 'BaseHTTPServer', 'Bastion', 'CGIHTTPServer', 'ColorPicker', 'ConfigParser', 'Cookie', 'DEVICE', 'DocXMLRPCServer', 'EasyDialogs']

Installation

The easy way is via pip:

pip install stdlib_list

The hard way is to clone this repository, go into the directory into which you cloned this repo, and do a

python setup.py install

Caveats

• No attempt was made to cull deprecated libraries. I just scraped the standard library page for the relevant version.

• For the sake of completion, if A.B is in the list, I also threw in A (eg, you’ll find xml, xml.etree, and xml.etree.ElementTree in the list, even though xml isn’t specifically listed in the TOC).

The Scraper

You shouldn’t need to fiddle around with the scraper, but in case you want to (or in case the Python Software Foundation decides to change the page layout of the standard library TOC page), just do:

from stdlib_list import scraper
scraper.scrape("2.7") # Scrape for 2.7 only (for debugging, mainly)
scraper.scrape() # Scrape for all versions listed above.
