Answer 1

# You can set your own rules

def check_password_strength(password):
    length = len(password)
    
    has_lower = False
    has_upper = False
    has_digit = False
    special_char = False

    lowuppdig = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890'

    for char in password:
        if char.islower():
            has_lower = True
        if char.isupper():
            has_upper = True
        if char.isdigit():
            has_digit = True
        if char not in lowuppdig:
            special_char = True

    if has_lower and has_upper and has_digit and special_char and length >= 10:
        return 'Strong'
    elif (has_lower or has_upper) and special_char and length >= 8:
        return 'Medium'
    else:
        return 'Weak'

passwords = ['aq1o@p9$XM', 'asW!W)(o', 'WSDFK!#Q', 'n*djskq*', 'WE3q#$']

for password in passwords:
    print(check_password_strength(password))
