How Python calls other. py functions within a. py file

Assume that a file named a.py needs to call the C (x, Y) function in the b.py file

If you are in the same directory, just

Import B if __name__ " __main__ " :    B.C (x, y)

If you just call a single function, you can also

 from Import C if __name__ " __main__ " :    C (x, y)

If a.py and b.py are located in different directories, you can use the following methods

(assuming b.py is located at the root of the D-disk)

1. The path where the reference is located

Import syssys.path.append ('d:/') Import B if __name__= ="__main__"    :Print b.pr (x, y)

2. Using Imp

Import IMPB=imp.load_source ('B','d:/b.py') Import B if __name__= ="__main__"    :Print b.pr (x, y)
