pylegacy

这个库旨在将Python新版本中的回滚内容移植到废弃的Python版本中。

pylegacy包的树状结构类似于Python标准库，即pylegacy包含pylegacy.abc、pylegacy.builtins、pylegacy.os等。如果某个功能有回滚版本可用，则可以通过从pylegacy命名空间导入该功能来使用它。

例如，Python 2.7中的os.makedirs缺少在Python 3.2中首次引入的exist_ok参数。为了启用此功能，需要将以下失败的代码片段替换为以下有效的代码片段

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'

...

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