Random password generator program using python.

Random password generator

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.

import string

import random

import sys

# Taking Password Length

pass_len = int(input("Enter Password Length (Min. 6 & Max. 8 ): "))

# Checking for password is in range or not

if pass_len < 6 or pass_len > 8:

    print("Invalid password length!!, Min. 6 & Max. 8 Characters Allowed")

    sys.exit(0)

# Password's letters count

letters_len = int(input("How many letters do you want? (Max. {} & Min. 0): ".format(pass_len)))

# Password's numbers count

num_len = int(input("How many numbers you want? (Max. {} & Min. 0): ".format(pass_len-letters_len)))

# Checking for valid inputs

if pass_len < (letters_len+num_len):

    print("Invalid inputs!! Letters length plus numbers length exceed total password length.")

    sys.exit(0)

sp_sym = 'Y'

if pass_len != (letters_len+num_len):

    sp_sym = input("Include any special symbol? (Y for Yes, N for No): ")

# Checking for valid character

if sp_sym not in ['Y','y','N','n']:

    print("Wrong Character!! Y/y for Yes and N/n for No ")

    sys.exit(0)

# Password without special symbols

if sp_sym == 'N' or sp_sym == 'n':

    print("Invalid inputs!! Letters length plus numbers length is not equal to password length.")

    sys.exit(0)

# Password with special symbols

if sp_sym == 'Y' or sp_sym == 'y':

    passw = random.sample(string.ascii_letters,letters_len) + random.sample(string.digits,num_len) \

             + random.sample(string.punctuation,pass_len-(letters_len+num_len))

else:

    passw = random.sample(string.ascii_letters+string.digits,pass_len)

# Shuffle random character's list

random.shuffle(passw)

# List to string conversion

pass_gen = ''.join(passw)

print("Your Password is generated: ",pass_gen)

Output

Enter Password Length (Min. 6 & Max. 8 ): 8

How many letters do you want? (Max. 8 & Min. 0): 4

How many numbers you want? (Max. 4 & Min. 0): 1

Include any special symbol? (Y for Yes, N for No): y
