我发现python.org有multiprocessing.Pipe
的官方文档,但是我的PyCharm IDE建议我导入multiprocessing.connection.Pipe
,它没有文档。内置帮助系统如下:
>>> 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,我应该使用哪些文档?
答案 0 :(得分:0)
我发现它实际上是同样的事情。在档案multiprocessing/context.py中,我找到了以下几行:
def Pipe(self, duplex=True):
'''Returns two connection object connected by a pipe'''
from .connection import Pipe
return Pipe(duplex)
