简单 Python 凯撒密码

Question

这是我的简单凯撒密码程序，但它运行不正常：

BASE = ord("a")
letter = input("Enter the message you want to encrypt:")
shift = int(input("The number you want to shift by: "))
lower_case = letter.lower
shift = BASE
new_strs = [""]
for character in lower_case:
    new_strs.append(chr(BASE + ord(character) - shift) %26)
print ("".join(new_strs))

我想创建模数 26。换句话说，如果要移动的数字是 27，则程序循环回到字母表 a-z 的开头。当您在消息中留下 space 时，我也遇到了问题。提前谢谢你。

    '''I added some parantheses and deleted the command shift = BASE '''

    BASE = ord("a")
    letter = input("Enter the message you want to encrypt:")
    shift = int(input("The number you want to shift by: "))
    # added ()
    lower_case = letter.lower()
    new_strs = [""]
    for character in lower_case:
        c   = (ord(character) - BASE + shift) % 26  
    new_strs.append(chr(c + BASE))
    print ("".join(new_strs))
