这取决于引用时要如何访问导入。
from urllib import request# access request directly.mine = request()import urllib.request# used as urllib.requestmine = urllib.request()
您也可以在导入时为自己添加事物别名，以简化操作或避免掩盖内置插件：
from os import open as open_# lets you use os.open without destroying the # built in open() which returns file handles.
