题解 | #字符串加解密#

python 利用ASCII码+1或者-1操作进行子母编码或解码
status值为1表示编码，-1表示解码

def encryption(password,status):
    result = ''
    for char in password:
        #数字位
        if char.isdigit():
            code = int(char) + status
            if code == -1:
                code = 9
            if code == 10:
                code = 0
            code = str(code)
        #小写子母位，a-z对应ASCII 97-122
        elif char.islower():
            asc = ord(char)
            code = asc + status
            if code == 123:
                code = 97
            if code == 96:
                code = 122
            code = chr(code).upper()
        #大写子母位，A-Z对应ASCII 65-90
        else:
            asc = ord(char)
            code = asc + status
            if code == 91:
                code = 65
            if code == 64:
                code = 90
            code = chr(code).lower()
        result += code
