I am trying to create a password generator program where the user can select for example 8 special characters, 5 uppercase letters and 10 lowercase letters to be generated into a password. So for the above example the password would be 23 characters long with 8 special characters, 5 uppercase letters and 10 lowercase letters. I have the input created but what I am unsure of is how to get the program to know that for example 8 special characters will be 8 random characters from string.punctuation for example.

This a sample code of how I am asking the user for their input.

while True:
  try:
    lower = list(string.ascii_lowercase)
    lower_low = 6
    lower_high = 24
    lower_choice = int(input("How many lower case letters would you like in your password? "))
    if lower_choice<lower_low or lower_choice>lower_high:
      print("The selection must be" ,lower_low,"or higher or", lower_high,"and lower. Please choose again. ")
      continue
    break
  except ValueError:
    print("Invalid input. Please try again.")

print("You have choosen", lower_choice,"lowercase letters to be used in your password.")

My Python knowledge is very rusty but I tried creating a function like the one below to see if it would take user inputs and match the number to string.punctuation for example and then create a random selection based on that but I am going wrong.

def password_gen():
  special = (string.punctuation)
  lower_choice = (string.ascii_lowercase)
  upper_choice = (string.ascii_uppercase)
  password = ''
  for p in range(38):
    password += random.choice(special+lower_choice+upper_choice)
    return password
  password = password_gen

  print(password)

Where should I look first to point me in the right direction. Again my knowledge is very rusty so let me know if my direction is completely off on this.

Thanks
