与文件同名的导入模块 [英] importing module with same name as file

问题描述

我要导入日志记录 https://docs.python.org/3/library /logging.html 放入名为logging.py的文档中.但是，当我尝试导入logging.handlers时，它失败了，因为我认为它是在文档中搜索处理程序功能，而不是从模块中导入.如何解决此问题，以便它将查找更高级别的日志记录，而不是查找文件内部?

I want to import logging https://docs.python.org/3/library/logging.html into a document named logging.py . When I try to import logging.handlers though, it fails because I believe it's searching the document for a handlers function, instead of importing from the module. How can I fix this so it will look for the higher level logging instead of looking inside the file?

推荐答案

您可以通过从python路径中删除当前目录(sys.path中的第一个目录)来实现此目的:

You can do it by removing current directory (first in sys.path) from python path:

import sys
sys.path = sys.path[1:]
import logging
print dir(logging)

测试:

$ python logging.py
