This article introduces the relevant knowledge of "what is the name attribute of the python module". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

When a module is first introduced by another program, its main program will run.

1. If you want a block in the module not to execute when the module is introduced, you can use the name attribute to make the block execute only when the module itself is running.

2. Each module has a name attribute, and when its value is' main', it indicates that the module itself is running, otherwise it is introduced.

Note: there is a double underscore under * name* and * main*, and the space in the middle is removed in this way.

Example

#! / usr/bin/env python#-*-coding:utf-8-*-# author: xulinjie time:2017/10/13def main (): if _ _ name__ = ='_ _ main__': print ('the program itself is running') else: print ('I'm from another module') main () print (_ _ name__) "what are the name properties of the python module".
