python-3.x - 我试图从用户那里获得对两个关键词不区分大小写的输入。如何使用两个主要关键字获得不区分大小写的输入？

Question

我正在尝试从不区分大小写并且有两个关键字但拒绝的用户那里获取输入。如何使用户自动输入以任何字母大小写的方式输入信息？我的任务是让用户在三次尝试中回答一个谜语，如果用户丢失了一条消息，则会显示。所以这就是我到目前为止所拥有的。

 print("There are two sisters. The former is produced by the latter while the latter produces the former. Who are these two sisters?")
print("YOU HAVE ONLY THREE TRIES OR YOU BECOME A ROTTEN EGG. Just kidding.")
answer = "seed and fruit"
guess = ""
guess_count = 0
guess_limit = 3
out_of_guesses = False

while guess != answer and not(out_of_guesses):
    if guess_count < guess_limit:
        guess = input("Enter your answer: ")
        guess_count += 1
    else:
        out_of_guesses = True

if out_of_guesses:
    print("YOU LOSE. Your a rotten egg, just kidding. The answer is seed and fruit.")
else:
    print("YOU WIN. Turns out your no rotten egg.")

我想让用户输入以种子和水果作为主要关键词的文本不敏感的输入。我该如何解决这个问题？
