注意事项:strip有神奇的魔力

参考代码:

email = input().strip()
N = int(input())
arr = []
for i in range(N):
    account = input().strip().split()
    password = list(account[1])
    if email in account:
        for i in range(len(password)):
            if password[i].isupper():
                password[i] = password[i].lower()
            else:
                password[i] = password[i].upper()
        arr.append(account[0] + " " + "".join(password))
if len(arr) == 0:
    print("empty")
else:
    for i in arr:
        print(i)
