Python – Password Generator

2 0

In this post I show how you can write a simple password generator with Python. With letters, characters and numbers, which are then generated into a password.

# Password Generator Project
import random
letters = ['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', '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']
numbers = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
symbols = ['!', '#', '$', '%', '&', '(', ')', '*', '+']

print("Welcome to the PyPassword Generator!")
nr_letters= int(input("How many letters would you like in your password?\n")) 
nr_symbols = int(input(f"How many symbols would you like?\n"))
nr_numbers = int(input(f"How many numbers would you like?\n"))

# Eazy Level - Order not randomised:
# e.g. 4 letter, 2 symbol, 2 number = JduE&!91
total_letter = ""
total_symbol = ""
total_number = ""
letter_random = random.sample(letters, nr_letters)
symbol_random = random.sample(symbols, nr_symbols)
number_random = random.sample(numbers, nr_numbers)

for letter in letter_random:
  total_letter += letter

for symbol in symbol_random:
  total_symbol += symbol

for number in number_random:
  total_number += number

# print(total_letter + total_symbol + total_number)

# Hard Level - Order of characters randomised:
# e.g. 4 letter, 2 symbol, 2 number = g^2jk8&P

final_total = total_letter + total_symbol + total_number
final = ''.join(random.sample(final_total, len(final_total)))

print(final)

The above code is output in the console and the following as an example:
