Dear Checkio I check this script in my python with "aaaaaaaaaaaaaaaaaa", it says "False". But "Run & Check" says this script doesn't work with "aaaaaaaaaaaaaaaaaa"! Please tell me why

def checkio(data): y = len(data) if y < 10: return "False" elif y>=10: if data.islower(): return "False" elif data.isupper(): return "False" else: if data.isdigit(): return "False" else: if data.isalpha(): return "False" else: return "True"
