为什么这个加密程序写了个寂寞？菜鸡哭泣

且停停停停

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

想把所有的a换成z，所有b换成y.......以此类推

for i in range(len(s)):
    if s[i] . isalpha():
        tx = lst1
        if s[i] in lst2:
            tx = lst2
        t += tx[- tx . index(s[i]) - 1]
    else:
        t += s[i]
print(t)
