Question

我不确定我做了什么，但现在当我玩游戏时，它在我输入我的选择（r，p或s）后结束它与验证有关吗？

这是代码：

    from random import randint

    computer = randint(1,3)

    r = "r"
    p = "p"
    s = "s"
    print ("The computer has chosen. Your turn")
    player = input ("r is Rock, p is Paper, and s is Scissors. Put your letter in HERE-----> ")

    a = 1
    while (a == 1):
            if (player not in(r,p,s)): 
                    player = input ("That wasn't r, p, or s. Please try again. r is Rock, p is Paper, and s is Scissors. Put your letter in HERE-----> ")
                    if (player in (r,p,s)):
                            a = 2

    if (computer == 1):
            AI = ("rock")

    if (computer == 2):
            AI = ("paper")

    if (computer == 3):
            AI = ("scissors")

    if (player == r and computer == 1):
            print ("lol draw")


    if (player == p and computer == 2):
            print ("lol draw")


    if (player == s and computer == 3):
            print ("lol draw")


    if (player == r and computer == 3):
            print ("You WIN!!!!!! AI chose " + AI)

    if (player == p and computer == 1):
            print ("You WIN!!!!!! AI chose " + AI)

    if (player == s and computer == 2):
            print ("You WIN!!!!!! AI chose " + AI)

    if (player == s and computer == 1):
            print ("You LOSE!!!!!! AI chose " + AI)

    if (player == r and computer == 2):
            print ("You LOSE!!!!!! AI chose " + AI)

    if (player == p and computer == 3):
            print ("You LOSE!!!!!! AI chose " + AI)

Answer 1

如果输入r，p或s，则输入无限循环。

a = 1
while (a == 1): #always enters
        if (player not in(r,p,s)): #if it is r or p or s it skips this
                player = input ("That wasn't r, p, or s. Please try again. r is Rock, p is Paper, and s is Scissors. Put your letter in HERE-----> ")
                if (player in (r,p,s)):
                        a = 2
        #and loops back, a being still 1

你正在寻找这样的东西：

player = None
while player not in (r, p, s):
    player = input ("That wasn't r, p, or s. Please try again. r is Rock, p is Paper, and s is Scissors. Put your letter in HERE-----> ")

Answer 2

清理此代码可以做很多事情，但问题来自于此：

while (a == 1):
        if (player not in(r,p,s)): 
                player = input ("That wasn't r, p, or s. Please try again. r is Rock, p is Paper, and s is Scissors. Put your letter in HERE-----> ")
                if (player in (r,p,s)): #this shouldn't be indented this far
                        a = 2           #this one either, obviously :)

Answer 3

现在你的程序陷入12-16行的无限循环中。你应该弄清楚为什么你自己，因为你会从中学到更多。

在样式注释中，使用过多的if语句使程序难以阅读。尝试找出一种更简洁的方法来回答问题而不必列举每个案例。
