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')
