Question

我正在尝试从艰难的方式学习python中的一个练习，并且我坚持做某事。我创建了一个函数，如果其中一个语句已经完成，我想把它放在另一个函数中。这是我如何尝试这样做的概述：

def room_1():
    print "Room 1"
    button_push = False

    while True:
       next = raw_input("> ")

        if next == "1":
            print "You hear a click but nothing seems to happen."
            button_push = True

        elif next == "2":
            print "You enter room 2"
            room_2()

def room_2():
    print "Room 2"

    while True:
        next =raw_input("> ")

        if next == "1" and button_push:
            print "You can enter Room 3"
            room_3()

如果满足了button_push，那么我希望在room_2中看到它。有人可以帮帮我吗？

您可以将button_push作为参数传递到下一个房间：

def room_1():
    print "Room 1"
    button_push = False

    while True:
       next = raw_input("> ")

        if next == "1":
            print "You hear a click but nothing seems to happen."
            button_push = True

        elif next == "2":
            print "You enter room 2"
            room_2(button_push)  # pass button_push as argument

def room_2(button_push):  # Accept button_push as argument
    print "Room 2"

    while True:
        next =raw_input("> ")

        if next == "1" and button_push:  # button_push is now visible from this scope
            print "You can enter Room 3"
            room_3()
