# 模块1
def some_function1():
    print("Function 1")
    # break语句
    break

def some_function2():
    print("Function 2")
    # return语句
    return

# 模块2
def some_function3():
    print("Function 3")
    # return语句
    return

def main():
    some_function1()
    some_function2()
    some_function3()

if __name__ == "__main__":
    main()

import sys

def some_function():
    print("Function 1")
    # return语句
    sys.exit()

def some_function2():
    print("Function 2")
    # return语句
    sys.exit()

def main():
    some_function()
    some_function2()

if __name__ == "__main__":
