适用于Caesar密码程序的Python中的标点翻译

Question

这是我一直在从事的Caesar密码程序，我想知道是否有一种方法可以使它不只是输出“。”。而是更改它。现在，它只输出末尾带有标点符号的字母。

import collections
import string
from collections import deque

def caesar(rotate_string, number_to_rotate_by): 

    upper = collections.deque(string.ascii_uppercase)
    lower = collections.deque(string.ascii_lowercase)

    upper.rotate(number_to_rotate_by)
    lower.rotate(number_to_rotate_by)

    upper = ''.join(list(upper))
    lower = ''.join(list(lower))

    return rotate_string.translate(str.maketrans(string.ascii_uppercase, upper)) .translate(str.maketrans(string.ascii_lowercase, lower))

our_string= input("What would you like to translate?" )


for i in range(len(string.ascii_uppercase)):
    print (i, "|", caesar(our_string, i))
