multiprocessing.Pipe和multiprocessing.connection.Pipe之间的区别

Question

I've found that python.org has official documentation for multiprocessing.Pipe , but my PyCharm IDE suggests me to import multiprocessing.connection.Pipe , which has no documentation. Built-in help system says as follows:

>>> 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

So what's the difference, where the docs and which one should I use?

Answer 1

I've figured out it's actually the same thing. In file multiprocessing/context.py I've found the following lines:

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