Question

def main():
    text = input("Please enter text")
    translated = caesar(text)

    print(text,"ciphered is", translated)



def caesar(text):



        key = int(input("Please enter key shift"))
        key = key % 26

        translated = ""
        for letter in text:
            if letter.isalpha():
                num = ord (letter)
                num += key
                if letter.isupper():
                        if num > ord ('Z'):
                             num -=26
                        elif num < ord ('A'):
                              num += 26
                        elif letter.islower():
                                  if num > ord ('z'):
                                        num -= 26
                        elif num < ord ('a'):
                             num += 26
                             translated += chr(num)
                else:
                        translated += letter
            return translated

main()

到目前为止，我有这个，但它实际上并没有改变这个词，例如，如果我将移位长度设为3，“Hello”转移到“o”，“a”不会转移在任何人都可以帮助我吗？

参考：“Caesar Cipher with Python”http://inventwithpython.com/chapter14.html

def main():
text = input("Please enter text: ")
translated = caesar(text)

print(text,"ciphered is", translated)



def caesar(message):
key = int(input("Please enter key shift: "))
key = -key
translated = ''

for symbol in message:
    if symbol.isalpha():
        num = ord(symbol)
        num += key

        if symbol.isupper():
            if num > ord('Z'):
                num -= 26
            elif num < ord('A'):
                num += 26
        elif symbol.islower():
            if num > ord('z'):
                num -= 26
            elif num < ord('a'):
                num += 26
        translated += chr(num)
    else:
        translated += symbol
return translated

main()

我正在尝试使用python创建一个Caesar密码，但我遇到了一些问题
