python - 猜谜游戏中输入多个相同的数字；循环停止工作？

Question

我一直在制作一个 4 猜数字游戏来学习 Python，它满足三个标准:

• 可重播
• 告诉玩家需要尝试多少次才能猜出正确答案
• 告诉玩家有多少个数字是正确的，以引导玩家找到正确的答案

我以为我符合标准，但游戏中出现了一个非常奇怪的错误。如果您尝试通过反复试验来猜测数字；游戏中断并且没有检测到您的答案是正确的。如果答案是“[1, 2, 3, 4]”，并且您尝试通过执行“[1, 1, 1, 1]”然后“[1, 2, 2, 2,]”来获得答案，最终获取“[1,2,3,4]”；程序会说这 4 个数字匹配，但不会让你赢得游戏，只会要求你再玩一次。这个错误真的要了我的命，我希望阅读的人能理解我想说的。

抱歉，代码块又大又长，但是问题可能出在此处的任何地方，但老实说我看不到它；我会尽可能地注释，以使其看起来不那么困惑。我只是...为什么会发生这种事!？

def compareLists(a, b): # to compare the guessed numbers and random numbers
    return list(set(a) & set(b))
rNums = random.sample(range(10), 4) # random list of numbers
def start():
    count = 0 # count for number of tries
    global rNums
    gNums = [] # guessed numbers
    print(rNums) # cheating to save time
    flag = True # to stop the guessing loop

    while flag:
        print("Get ready to guess 4 numbers!")
        for i in range(0, 4): # asks the player 4 times to input a number
            x = int(input("Guess: "))
            gNums.append(x) # puts numbers in guessed numbers

        comparison = len(compareLists(rNums, gNums)) # storing the length of the list of similar numbers
        isCorrect = gNums == rNums # to check if lists are the same
        print("You guessed: ", gNums) # telling player what they have guessed

        if isCorrect: # if the lists are the same

            if count > 1:
                print("You win!! It only took you %d tries!" %count) # telling the player how many tries it took
            else: #congratulating the player on a flawless guess
                print("I CAN'T BELIEVE WHAT I'M SEEING!!!")
                print("YOU GOT IT IN ONE GO!!")
            count += 1 # increment count
            rNums = random.sample(range(10), 4) # generate new numbers
            gNums.clear()
            pAgain = input("Play again?")
            if pAgain.lower() in ('y', 'yes'): # replaying the game
                continue
            elif pAgain.lower() in ('n', 'no'):
                flag = False
            else:
                print("Incorrect syntax!")

        else:
            print("You guessed " + str(comparison) + " numbers right, keep guessing!") # tells the player how many numbers are similar so the player can get a more educated guess
            gNums.clear() # empties guessed numbers
            count += 1 # increment count
            print("Number of tries so far: %d" %count) # showing player number of tries so far

用于检查两个列表是否相同的比较不起作用:

isCorrect = gNums == rNums # to check if lists are the same

上面的代码检查两个列表是否相同，但元素的顺序必须相同。

对于您的测试，您只需检查匹配的数字(忽略顺序)是否等于数字列表的长度:

isCorrect = comparison == len(gNums) # to check if lists are the same

有关比较列表(无论顺序如何)的更多信息，请参阅此 answer .

此外，在与 1 进行比较之前，您应该增加计数，否则程序会说您只进行了一次，而实际上您进行了两次。
