        for c in pw:

            elif c.isdigit():
                num += 1

        if upper != 0 and lower != 0 and num != 0:
            print(True)

        else:
            print(False)

    else:
        print(False)
else:
    print(False)

above is my code, I checked with checkio("ULFFunH8ni") with pycharm, everything are correct, but it shows fail when i submit it
