打破内部循环 python

Question

我只想退出放置中断的内部循环。使用 continue 可以工作，但我认为 break 应该退出最内层的循环，但它似乎退出了整个程序。 break 是怎么回事？

counter = 0

while counter == 0:

    print "You enter a dark room with two doors.  Do you go through door #1 or door #2?"

    door = raw_input("> ")

    if door == "1":
        print "There's a giant bear here eating a cheese cake.  What do you do?"
        print "1. Take the cake."
        print "2. Scream at the bear."

        bear = raw_input("> ")

        if bear == "1":
            print "The bear eats your face off.  Good job!"
        elif bear == "2":
            print "The bear eats your legs off.  Good job!"
        else:
            print "Well, doing %s is probably better.  Bear runs away." % bear
            break

    else:
        print "You stumble around and fall on a knife and die.  Good job!"

Answer 1

你的代码中只有一个循环，break 正在退出它，"if" 不是循环，它是一个语句...即使你有多个，它们也是语句，并且 break， will "break" 来自你的 while 循环，而不是 "if" 语句。

Answer 2

break- Jumps out of the closest enclosing loop (past the entire loop statement)

在你的情况下，这正是它在做什么。 if 不是循环语句，它是控制语句。

您只有一个循环，即 while。
