什么是.在Python中的import语句中是什么意思? [英] What does a . in an import statement in Python mean?

问题描述

我正在查看Python的multiprocessing模块的代码，其中包含以下行:

I'm looking over the code for Python's multiprocessing module, and it contains this line:

from ._multiprocessing import win32, Connection, PipeConnection

代替

from _multiprocessing import win32, Connection, PipeConnection

细微差别是_multiprocessing之前的时期.那是什么意思?为什么要月经?

the subtle difference being the period before _multiprocessing. What does that mean? Why the period?

推荐答案

这是显式相对进口.这意味着从当前程序包导入.

That's the new syntax for explicit relative imports. It means import from the current package.
