while True:
try:

letterlst = []
string_out =''
for i in range(26):
letterlst.append(chr((ord("a")+i)))

if word not in new_key:
new_key.append(word)
for letter in new_key:
letterlst.remove(letter)
new_key.extend(letterlst)
for str in string_in:
if str.isalpha():
index= ord(str)-97
string_out+=new_key[index]
else:
string_out+=str
print(string_out)
except:
break
重点几个python function:
- ord("a") 根据给定的character 返回Unicode code (ord("a")=97)
- chr() 参数是一个范围在255内的整数,返回对应的字符 (chr()和ord()可以看作互逆的函数)
