解法1（Python3）:

import re
import sys

for line in sys.stdin:
    line = line.strip()
    if len(line) <= 8:
        print('NG')
        continue
    count = 0
    if re.search('[a-z]+', line) is not None:
        count += 1
    if re.search('[A-Z]+', line) is not None:
        count += 1
    if re.search('[0-9]+', line) is not None:
        count += 1
    if re.search('[^a-zA-Z0-9]+', line) is not None:
        count += 1
    if count < 3:
        print('NG')
        continue
    for i in range(len(line)-3):
        if line.count(line[i:i+3]) > 1:
            print('NG')
            break
    else:
        print('OK')

解法2（Python3）：

import re

try:
    while True:
        s = input()
        a = re.findall(r'.*(.{3,}).*\1', s)
        b1 = re.findall(r'[0-9]', s)
        b2 = re.findall(r'[A-Z]', s)
        b3 = re.findall(r'[a-z]', s)
        b4 = re.findall(r'[^0-9A-Za-z]', s)
        if [b1, b2, b3, b4].count([]) <= 1 and a == [] and len(s) > 8:
            print('OK')
        else:
            print('NG')
except:
    pass
