jupyter book解密文

• 解密方法可预先约定好一组字母密码存放在元组code密码表中，code[0]code[9]分别表示数字“0”“9”对应的密码；输入欲解密的密文（Ciphertext）并回车（输入字母“q”将推出程序），根据密码表转换成明文（Plaintext，码表中无法转换的代码用“?”代替，最后显示在标签上。）

用字典

dic ={"0":"h","1":"n","2":"b","了":"X","4":"m","5":"a","6":"q","7":"f","8":"e","9":"y"," ":" "}
data = input()
lst = ''
for i in data:
    lst+=dic[i]
print(lst)
