Let's generate a password of length n using a while loop and random.choice, this will be a string of random characters, e.g. a62xB95. Allow the user to enter the value of n, remember to convert its type to an int, as input returns a string. Hint: random.choice can be used to pick a character out of a string, as well as an element out of a list.
Ask the user for how many lowercase letters, uppercase letters, numbers, and special characters they'd like in their password. You do not want the pieces in order (e.g. 3 lowercase letters followed by 3 uppercase letters...). You can use list(password_string) or password_string.split('') to convert the string to a list, random.shuffle(password_list) to shuffle it, and then ''.join(password_list) to turn it back into a string.
