Python 3：如何从另一个文件调用函数并将参数传递给该函数？

Question

I want to call a function from another file and pass arguments from current file to that file. With below example, In file bye.py I want to call function " me " from " hi.py " file and pass " goodbye " string to function " me ". How to do that ? Thank you :)

I have file hi.py

def me(string):
    print(string)
me('hello')

bye.py

from hi import me
me('goodbye')

What I got:

hello
goodbye

What I would like:

goodbye

Generally when you create files to be imported you must use if __name__ == '__main__' which evaluates to false in case you are importing the file from another file. So your hi.py may look as:

def me(string):
    print(string)

if __name__ == '__main__':
    # Do some local work which should not be reflected while importing this file to another module.
    me('hello')
