Problem-

Write a programme, which generates a random password for the user. 

Ask the user how long they want their password to be, and how many letters 

and numbers they want in their password. Have a mix of upper and lowercase 

letters, as well as numbers and symbols. 

The password should be a minimum of 6 characters long.

Solution-

import random
import array

MAX_LEN = int(input("Enter the length of the Password you want (minimum length should be 6): "))

NODigits = int(input("Enter the number of digits you want in Password: "))

NOLocase = int(input("Enter the number of Lower Case you want in Password: "))

NOUpcase = int(input("Enter the number of Upper Case you want in Password: "))

NOSymbol = int(input("Enter the number of symbols you want in Password: "))


DIGITS = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']

LOCASE_CHARACTERS = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h',
                     'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p',
                     'q', 'r', 's', 't', 'u', 'v', 'w', 'x',
                     'y', 'z']

UPCASE_CHARACTERS = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H',
                     'I', 'J', 'K', 'L', 'M', 'N', 'O', 'p',
                     'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X',
                     'Y', 'Z']

SYMBOLS = ['@', '#', '$', '%', '=', ':', '?', '.', '/', '|', '~', '>',
           '*', '(', ')', '<', '&']

           
COMBINED_LIST = DIGITS + UPCASE_CHARACTERS + LOCASE_CHARACTERS + SYMBOLS

rand_digit = random.choice(DIGITS)
rand_upper = random.choice(UPCASE_CHARACTERS)
rand_lower = random.choice(LOCASE_CHARACTERS)
rand_symbol = random.choice(SYMBOLS)

i = 1
while(i < NODigits):
    rand_digit = rand_digit + random.choice(DIGITS)
    i = i + 1

i = 1
while(i < NOLocase):
    rand_upper = rand_upper + random.choice(UPCASE_CHARACTERS)
    i = i + 1

i = 1
while(i < NOUpcase):
    rand_lower = rand_lower + random.choice(LOCASE_CHARACTERS)
    i = i + 1

i = 1
while(i < NOSymbol):
    rand_symbol = rand_symbol + random.choice(SYMBOLS)
    i = i + 1

temp_pass = rand_digit + rand_upper + rand_lower + rand_symbol

for x in range(MAX_LEN - (NODigits + NOLocase + NOUpcase + NOSymbol)):
    temp_pass = temp_pass + random.choice(COMBINED_LIST)

temp_pass_list = array.array('u', temp_pass)
random.shuffle(temp_pass_list)

password = ""for x in temp_pass_list:
    password = password + x

print("\nGenerated Password: ",password)

OUTPUT:

Enter the length of the Password you want (minimum length should be 6): 16
Enter the number of digits you want in Password: 4
Enter the number of Lower Case you want in Password: 4
Enter the number of Upper Case you want in Password: 4
Enter the number of symbols you want in Password: 4
Generated Password:  ~08=H2R>kCb$kAx0
