multiprocessing.Pipe与multiprocessing.connection.Pipe的区别

Question

我发现python.org有multiprocessing.Pipe的官方文档，但我的PyCharm集成开发环境建议我导入multiprocessing.connection.Pipe，它没有文档。内置的帮助系统显示如下：

>>> from multiprocessing import Pipe as P1
>>> from multiprocessing.connection import Pipe as P2    
>>> help(P1)
Help on method Pipe in module multiprocessing.context:

Pipe(duplex=True) method of multiprocessing.context.DefaultContext instance
    Returns two connection object connected by a pipe

>>> help(P2)
Help on function Pipe in module multiprocessing.connection:

Pipe(duplex=True)
    Returns pair of connection objects at either end of a pipe

那么有什么区别呢，文档在哪里，我应该使用哪个文档呢？

Answer 1

我发现这其实是一回事。在文件multiprocessing/context.py中，我发现了以下几行：

def Pipe(self, duplex=True):
    '''Returns two connection object connected by a pipe'''
    from .connection import Pipe
    return Pipe(duplex)
