def isValidPassword(password):

    if len(password) >= 10:

            if s.isalpha():
                if s.islower():
                    lower = True
                else:
                    upper = True
            elif s.isdigit():
                num += 1
            else:
                sym += 1

    if upper and lower and num >= 3 and sym >= 2:
