Python 在输入字符串中移动值

我正试着做一个凯撒密码，我已经很接近了。问题是我的输出只打印出一个字母，而不是整行加密。E是英语中使用频率最高的字母，因此我们的想法是找出E和输入中使用频率最高的字母之间的距离。然后把所有东西移到那个距离。我是python新手，所以还不是很好。非常感谢！以下是我目前掌握的代码：

maximum_character = unciphered_text[0]
maximum_count = unciphered_text.count(unciphered_text[0])
for char in unciphered_text:
    if char is not " ":
        if unciphered_text.count(char) > maximum_count:
            maximum_character = char

print("The most frequent character used is: ", maximum_character) 

ASCII_maximum = maximum_character.lower()
ASCII_number = ord(ASCII_maximum)
print(ASCII_number)

shift_distance = ord('e')-ASCII_number
print("The shift distance is: ", shift_distance)

def caesar_cipher(unciphered_text, shift_distance):
    ciphered_text = ""
    for char in unciphered_text:
        cipher_process = ord(char)+shift_distance
        post_translation = chr(cipher_process)
        ciphered_text += post_translation 
        return ciphered_text 

answer = caesar_cipher(unciphered_text, shift_distance)
print(answer)

您在

caesar\u cipher

函数中误入了返回语句

将return语句从循环中移出：

def caesar_cipher(unciphered_text, shift_distance):
    ciphered_text = ""
    for char in unciphered_text:
        cipher_process = ord(char)+shift_distance
        post_translation = chr(cipher_process)
        ciphered_text += post_translation 
    return ciphered_text

成功了！非常感谢你！我不知道python的缩进有多敏感。你认为我可以用其他方法改进我的代码吗？或者它能按原样完成工作吗？再次感谢你，真的。我很惊慌。
