这里注意判断大小写是isupper、islower、isdigit 以及循环 while True: try: s = input() except: break

def get_result(code):
    if len(code)<8:
        return "NG"
    up = 0
    low = 0
    di = 0
    other = 0
    for i in code:
        if i.isupper():
            up = 1
        elif i.islower():
            low = 1
        elif i.isdigit():
            di = 1
        else:
            other = 1
    if up+low+di+other<3:
        return "NG"
    re = []
    for i in range(3, len(code)):
        split = code[i-3:i]
        if split in re:
            return "NG"
        else:

    return "OK"
while True:
    try:

        result = get_result(code)
        print(result)
