如何解决 NameError: name 'api' is not defined 错误代码？

Question

I am trying to use send a tweet through python code. But for some reason the code returns an error code: NameError: name 'Girl' is not defined . All my code seems to be intended properly so I'm not sure what the issue is. Unfortunately I cannot share the simple_twit library as it restricted against University guidelines but I feel like I made a simple mistake that I am not seeing so a point to the right direction would be appreciated.

Here is my code:

import sys
import time
import simple_twit
import random



def main():
    api = simple_twit.create_api()
    simple_twit.version()

    def boyname():
        global Boy
        result = random.choice(Boy)
        print('Your future son’s name can be', result)
        Boy.remove(result)

    def girlname():
        global Girl
        result = random.choice(Girl)
        print('Your future daughter’s name can be', result)
        Girl.remove(result)

    sendtweet = simple_twit.send_tweet(api, girlname())
    print()


if __name__ == "__main__":
       main()

Answer 1

You have to define the global variable outside any function.
