如果输入是特定字符串，则重复 while 循环

Question

我刚刚创建了一个小游戏，如果用户愿意，我想重复它。 我创建了一个输入，然后尝试将 guess_count 变量设置回 0，所以我认为它会再次触发 while 循环。

secret_number = 8
guess_count = 0
guess_limit = 3
while guess_count < guess_limit:
    guess = int(input("Guess the number: "))
    guess_count += 1
    if guess == secret_number:
        print("You won!")
        break
else:
    print("Sorry, you failed!")
    try_again = input("Try again? ")
    if try_again == "yes":
        guess_count = 0

Answer 1

playing = True

secret_number = 8

while playing:
    guess_count = 0
    guess_limit = 3

while guess_count < guess_limit:
    guess = int(input("Guess the number: "))
    guess_count += 1
    if guess == secret_number:
        print("You won!")
        break
else:
    print("Sorry, you failed!")
try_again = input("Try again? (yes/no) ")
if try_again == "no":
    playing = False

在else块中将guess_count设置回0将不会再次触发循环。 这是因为else块是在循环退出后执行的。 您可能希望将重新启动循环的逻辑移到循环本身中。 例如。

secret_number = 8
guess_count = 0
guess_limit = 3
while True:
    if guess_count >= guess_limit:
        print("Sorry, you failed!")
        try_again = input("Try again? ")
        if try_again == "yes":
            guess_count = 0
            continue
        else:
            break
    else:
        guess = int(input("Guess the number: "))
        guess_count += 1
        if guess == secret_number:
            print("You won!")
            break
