为什么这个加密程序写了个寂寞？菜鸡哭泣
s=list(input())lst1=['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
lst2=['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z']
for i in s:
if i in lst1:
p=lst1.index(i)
i=lst1[-p]
elif i in lst2:
k=lst2.index(i)
i=lst2[-k]
else:
i=i
print("".join(s))
输出和输入一模一样{:10_266:}
