While循環在Python中不起作用

Question

while循環無法正常工作。 Again變量將決定是否將再次執行while循環。 如果再次= 1，則將執行while循環，並且程序將再次運行。 如果再次= 0，則不會。

由於某種原因，再次始終為= 1，因此無論如何，總是執行while循環。 有人注意到代碼中的錯誤嗎？

 score = 0
 loops = 0
 again = 1
 while (again != 0):
    import random
    real = random.randint(1,9)
    fake1 = random.randint(1,9)
    fake2 = random.randint(1,9)
    comb = random.randint(1,9)
    rep = 0
    guess = 0

    if (comb == 1 or comb == 2 or comb == 3):
        print(real, fake1, fake2)
        loops += 1
        guess = int(input("Choose between these numbers"))
        if (guess == real):
            score += 1
            print ("Congrats!")
        else:
            print ("Wrong, better luck next time!")
    if (comb == 4 or comb == 5 or comb == 6):
        print (fake1, fake2, real)
        loops += 1
        guess = int(input("Choose between these numbers"))
        if (guess == real):
            score += 1
            print ("Congrats!")
        else:
            print ("Wrong, better luck next time!")

    if (comb == 7 or comb == 8 or comb == 9):
        print (fake2, real, fake1)
        loops += 1
        guess = int(input("Choose between these numbers"))
        if (guess == real):
            score += 1
            print ("Congrats!")
        else:
            print ("Wrong, better luck next time!")
    again == int(input("Do you wanna go again?"))
    print(again)

Answer 1

在將值分配給再次調用的變量時，您可以使用比較運算符：

again == int(input("Do you wanna go again?"))

您必須刪除一個等號：

again = int(input("Do you wanna go again?"))

Answer 2

again == int(input("Do you wanna go again?"))

這不會做您想的，因為==表示它正在檢查此語句是否為真。 您想要一個=。
