Asking the user for input until they give a valid response (22 个回答)

我正在寻找一种方法来实现“按 Y 继续，N 取消”提示。

我目前的实现方式是

Prompt = None
# Loop until the user inputs a valid answer
while Prompt not in ("yes", "y", "n", "no"):
    Prompt = input("Do you wish to continue? answer y or n\n")
    if Prompt == 'y' or == 'yes':
        state = 2 # switch state to processing state
    elif Prompt == 'n' or == 'no': # cancel
        break

有没有更有效的方法来实现这个提示？

是的，只需尝试以下操作即可。

while True:
    Prompt = input("Do you wish to continue? answer y or n\n")
    if Prompt in ['y', 'yes']:
        state = 2 # switch state to processing state
    elif Prompt in ['n', 'no']:
        break
