我使用atom作为编辑器在cygwin上运行它。 Python3。
您好，
基本的Python问题真让我感到困惑。我在SO上环顾四周，发现了很多关于类似问题的问题，但找不到涵盖我所面临问题的问题。
在我详细介绍之前;这是我正在进行的一项任务，如果你不想泄漏所有的豆类，那么就给我一些指导。
我的任务是将一个聊天机器人分成两个文件，一个处理main（）函数，另一个处理main（）使用的输入选择所有可能的函数。
由于某种原因，两个文件编译正常，但是当我调用main.py
时（通过＆gt; python main.py // // //或by＆gt; ./main.py）
我根本没有提示。在尝试使用marvin.py时，我也没有得到提示。
两个文件都在同一目录中。
这是main（）：
#!/usr/bin/env python3
import marvin
def main():
"""
This is the main method, I call it main by convention.
Its an eternal loop, until q is pressed.
It should check the choice done by the user and call a appropriate
function.
"""
while True:
menu()
choice = input("--> ")
if choice == "q":
print("Bye, bye - and welcome back anytime!")
return
elif choice == "1":
myNameIs()
elif choice == "2":
yearsToSec()
elif choice == "3":
weightOnMoon()
elif choice == "4":
minsToHours()
elif choice == "5":
celToFahr()
elif choice == "6":
multiplyWord()
elif choice == "7":
randNumber()
elif choice == "8":
sumAndAverage()
elif choice == "9":
gradeFromPoints()
elif choice == "10":
areaFromRadius()
elif choice == "11":
calcHypotenuse()
elif choice == "12":
checkNumber()
else:
print("That is not a valid choice. You can only choose from the menu.")
input("\nPress enter to continue...")
if __name__ == "__main__":
main()
正如您所看到的，我在加载环境变量后导入了marvin。 编译任一文件时都没有缩进错误或其他任何错误（如上所述）。
免责声明：我认为你不需要阅读marvin，tbh ......
这是marvin.py：
#!/usr/bin/env python3
from random import randint

def meImage():
"""

if __name__ == "__main__":
main()
不应缩进。
在您当前的代码中，main()方法在else块中运行，但您永远不会到达，因为程序无法启动，因为您只是定义 main()方法，但从不执行。
取消它，它将被执行，因为它不再是在函数定义中。
答案 1 :(得分：0)
marvin.py中定义的函数不是main.py中的全局变量;他们是marvin模块对象的成员。所以，这个：
elif choice == "1": myNameIs()
应改为：
elif choice == "1": marvin.myNameIs()
对于main.py使用marvin.py函数的其他地方也是如此。
