我对Python相当陌生,已经开始制作一些有趣的小游戏来记住它是如何工作的。我遇到了一个地方,我想在while循环中使用多个条件,但却不知道如何去做。我在这里看到一些人用数字等来做这件事,但我用的是字母,我做的或搜索的似乎都不管用。这就是我目前所得到的。如果输入是大写的,或者不循环输入。在
ANS = input("\tA/B: ")
if ANS == "A":
print("They beat you up and stole all of your stuff. You should have run away.")
del BAG[:]
print("You now have", len(BAG), "items in your bag.")
elif ANS == "a":
print("They beat you up and stole all of your stuff. You should have run away.")
del BAG[:]
print("You now have", len(BAG), "items in your bag.")
elif ANS == "B":
print("You got away but they stole something from you.")
ran_item = random.choice(BAG)
BAG.remove(ran_item)
print("You now have", len(BAG), "items in your bag")
print("They are:", BAG)
elif ANS == "b":
print("You got away but they stole something from you.")
ran_item = random.choice(BAG)
BAG.remove(ran_item)
print("You now have", len(BAG), "items in your bag")
print("They are:", BAG)
while ANS != "A" or "a" or "B" or "b":
print("You must make a choice...")
ANS = input("\tA/B: ")
任何帮助都会很棒的。提前谢谢。在
Python解释while循环的条件如下:
而且,它的计算结果总是
True
,因为非空字符串的计算结果总是True
。若要解决此问题,可以改用^{} :
^{pr2}$not in
将测试在元组("A", "a", "B", "b")
中是否可以找到{您还可以在这里使用^{} 来缩短元组的长度:
在这种情况下,我能想到的最简单的方法是:
或者更广泛地说
^{pr2}$相关问题 更多 >
