按照这个课后习题,答案是“ilovefishc”。
我写的代码运行结果为 ['u', 'i', 'l', 'o', 'v', 'e', 'f', 'i', 's', 'd', 'h', 'c'] ,不知道哪里有问题,为什么还会有“u”和“d”出现??
求大佬们帮我看看
def findsecret(strings):
    secrets = []
    length = len(strings)
    for i in range(4, length-4):
        if (strings[i].islower() and
            strings[i+1:i+4].isupper() and
            strings[i-3:i].isupper() and
            strings[i+4].islower() and
            strings[i-4].islower()):
            secrets.append(strings[i])
    print(secrets)
