import random       # This module is required for the "choices()" method we will use

    # Force "length" to be between 8 and 12 characters
    # This is a neat Pythonic approach, rather than a naive if/else test
    length = max(length, 8)
    length = min(length, 12)

    # Now we will create our password, firstly as a list
    # Start with 2 uppercase letters chosen at random using choices()
    password = random.choices(string.ascii_uppercase, k=2)

    # Then add 2 random lowercase letters
    password.extend(random.choices(string.ascii_lowercase, k=2))

    # Must include 2 digits
    password.extend(random.choices(string.digits, k=2))

    # Must include 2 "punctuation" characters
    password.extend(random.choices(string.punctuation, k=2))

    # The ppassword now is of length 8. If we want it longer we can extend it
    # with any combination of letters digits and punctuation

    if length > 8:
        mixture = string.ascii_letters + string.digits + string.punctuation
        password.extend(random.choices(mixture, k=length-8))

    # Shuffle the list
    random.shuffle(password)
    # Convert the list to a string and return it

# Generate some sample passwords of length 3 to 14, (these lengths will get constrained to 8 through 12)
