Documentation

pylegacy

This library aims to provide backports from Python newer versions into abandoned Python versions.

The pylegacy package tree structure resembles that of the Python standard libraries, i.e. pylegacy consists of pylegacy.abc, pylegacy.builtins, pylegacy.os, and so on. If a backport is available for a piece of missing functionality, it can be used by importing the functionality from the pylegacy namespace.

For example, os.makedirs in Python 2.7 lacks the exist_ok argument, first introduced in Python 3.2. To enable this functionality, one would replace the following failing code snippet:

import os
os.makedirs("example_folder", exist_ok=True)
# Traceback (most recent call last):
#   File "<stdin>", line 1, in <module>
# TypeError: makedirs() got an unexpected keyword argument 'exist_ok'

with the following working code snippet:

from pylegacy import os
os.makedirs("example_folder", exist_ok=True)
