Random license plates

 The simple program makes a simple 3 letter and 3 digit license plate, in the form LLL-DDD. It just picks 3 random letters from a list of letters, then 3 random digits.

def license_plate():
    alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
    i = 0
    alphabet_array = []
    while i != len(alphabet):
        alphabet_array.append(alphabet[i])
        i += 1
    output = ""
    for x in range(0, 3):
        output += alphabet[random.randint(0, 25)]
    output += "-"
    for x in range(0, 3):
        output += str(random.randint(0, 9))
    return output
