题解 | 简单密码

ps = input().strip()
a = ''							#用于保存
for i in ps:					#对于简单密码中的每一项
    if "A" <= i < "Z":			#大写字母先转换为小写再后移一位
        i = chr(ord(i) + 33)
        a = a + i
    elif i == 'Z':				#特殊的Z的ACSII码加33不是a
        i = 'a'
        a = a + i
    
    elif i in 'abc':		#字符串 加引号
        a = a + '2'
    elif i in 'def':
        a = a + '3'
    elif i in 'ghi':
        a = a + '4'
    elif i in 'jkl':
        a = a + '5'
    elif i in 'mno':
        a = a + '6'
    elif i in 'pqrs':
        a = a + '7'
    elif i in 'tuv':
        a = a + '8'
    elif i in 'wxyz':
        a = a + '9'

    elif i.isdigit():
        a = a + i		#变量 不加引号

print(a)

思路见代码注释！！！
