$\hspace{15pt}$ 规定这样一种密码的变换方法：
$\hspace{23pt}\bullet\,$ 对于密码中的小写字母，参考九键手机键盘，将它们映射为对应的数字，具体地， $\mathtt{abc}$ 对应数字 $2$ 、 $\mathtt{def}$ 对应数字 $3$ 、 $\mathtt{ghi}$ 对应数字 $4$ 、 $\mathtt{jkl}$ 对应数字 $5$ 、 $\mathtt{mno}$ 对应数字 $6$ 、 $\mathtt{pqrs}$ 对应数字 $7$ 、 $\mathtt{tuv}$ 对应数字 $8$ 、 $\mathtt{wxyz}$ 对应数字 $9$ ；
$\hspace{23pt}\bullet\,$ 对于密码中的大写字母，先将其转换为小写，然后向后移动一位，即 $\mathtt{Z}$ 转换为 $\mathtt{a}$ ， $\mathtt{A}$ 转换为 $\mathtt{b}$ ， $\mathtt{B}$ 转换为 $\mathtt{c}$ ， $\cdots$ ， $\mathtt{Y}$ 转换为 $\mathtt{z}$ ， $\mathtt{Z}$ 转换为 $\mathtt{a}$ 。
$\hspace{23pt}\bullet\,$ 对于密码中的数字，保持不变。

$\hspace{15pt}$ 现在，请你将给定的密码按照上述规则进行变换。

输入描述:

在一行上输入一个长度为  的字符串  ，代表给定的密码。

输出描述:

在一行上输出一个字符串，代表变换后的密码。

简单思路，先创建一个dict用来存储这些转化

大写的转化那里需要用到ASC2码的转化

大写先用str.lower()转小写

然后用ord转ASC码

如果是z的话，需要手动定义等于z

其他的子需要将asc码+1就得到了下一个字母的asc码

import sys
 
for line in sys.stdin:
    a = line.split()
    str_input = a[0]


change_dict = {"1":1,"a":2,"b":2,"c":2,"d":3,"e":3,"f":3,"g":4,"h":4,"i":4,
              "j":5,"k":5,"l":5,"m":6,"n":6,"o":6,"p":7,"q":7,"r":7,"s":7,
              "t":8,"u":8,"v":8,"w":9,"x":9,"y":9,"z":9,"0":0}
result = ""
for i in str_input:
    if(i.isupper()):
        #先转化小写
        up_i = i.lower()

        #转化码
        ac2_up_i = ord(up_i)
        if(ac2_up_i == ord("z")):
            ac2_up_i = ord("a")
            result = result + chr(ac2_up_i)
        else:
            result = result + chr(ac2_up_i+1)
    elif(i.isdigit()):
        result = result + str(i)
    else:
        result = result + str(change_dict[i])
