我正在尝试制作一个脚本，将消息的每个字母旋转 13 个字母，创建一个简单的密码。我的密码正确地旋转了字母，我遇到的问题是它只将它加密为大写字母。

例如，对于我输入“Hello！World”，它应该返回“Uryyb！Jbeyq”，但它返回“URYYB！JBEYQ”

uppercase = ['A','B','C','D', 'E', 'F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z']
lowercase = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
ciphered = ""
for i in message:
    if i.isalpha():
        if i in uppercase: # checks if letter (i) is an upper case and treats it as such
            letter = uppercase.index(i)
            rotated = uppercase[(letter + 13) % 26] # used to loop through alphabet
            ciphered = ciphered + rotated
        else:
            letter = lowercase.index(i) 
            rotated = uppercase[(letter + 13) % 26] # used to loop through alphabet
            ciphered = ciphered + rotated
    else:
        ciphered = ciphered + i
return ciphered

小错误，在 else 条件下，您使用的是大写列表。将其更改为小写：

uppercase = ['A','B','C','D', 'E', 'F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z']
lowercase = ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
ciphered = ""
for i in message:
    if i.isalpha():
        if i in uppercase: # checks if letter (i) is an upper case and treats it as such
            letter = uppercase.index(i)
            rotated = uppercase[(letter + 13) % 26] # used to loop through alphabet
            ciphered = ciphered + rotated
        else:
            letter = lowercase.index(i) 
            rotated = lowercase[(letter + 13) % 26] # used to loop through alphabet
            ciphered = ciphered + rotated
    else:
        ciphered = ciphered + i
return ciphered
