# Creating a password generator in Python

# string library to generate the password 
import string 
# generate secure and random passwords
import random

# create a function for the password generator
def gen():
    # create a variable `s1` to give the uppercase letters
    s1 = string.ascii_uppercase

    # create a variable `s2` to give the uppercase letters
    s2 = string.ascii_lowercase

    # create a variable `s3` to give the digits
    s3 = string.digits

    # create a variable `s4` to give the special characters
    s4 = string.punctuation  

    # we want the password generator to take the input from the user, Create an input variable for it

    passlen = int(input("Enter the password length\n"))

    # create a list, to add all the variables into a list called `s`

    s = []
    s.extend(list(s1))
    s.extend(list(s2))
    s.extend(list(s3))
    s.extend(list(s4))

    # randomly shuffle the variables

    random.shuffle(s)

    # pass the list s from 0 till the length of the password gotten from the user 
    pas = ("".join(s[0:passlen]))
    print(pas)

    # when you run the file you can see that all the variables and special symbols are saved as a list
