python - python导入中的大小写标准

Question

在 python 中有很多用于导入模块的标准缩写。我经常看到

import matplotlib.pyplot as plt
import numpy as np
import networkx as nx

我注意到所有这些都是小写的。我想不出任何异常(exception)。但是，它是区分大小写的，所以我们当然可以使用大写字母。是否有任何关于此的 PEP 标准？特别是，使用大写名称创建模块并使用大写导入它们会不会有任何问题？

例如:

import MyClass as MC
import TomAndJerry as TaJ

(请注意 - 我对个人意见并不感兴趣 - 而是是否有官方标准)

Answer 1

There are indeed official standards :

Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

When an extension module written in C or C++ has an accompanying Python module that provides a higher level (e.g. more object oriented) interface, the C/C++ module has a leading underscore (e.g. _socket ).
