Today ChatGPT suggested me to make a password generator. First I share the exercise, then my solution 🙂
Exercise: Password Generator
Write a Python program that generates random passwords based on user-defined criteria. The program should perform the following steps:
- Ask the user for the desired length of the password (e.g., 8 characters, 12 characters, etc.).
- Ask the user if they want to include uppercase letters, lowercase letters, digits, and special characters in the password (e.g., "Yes" or "No" for each category).
- Generate a random password that meets the user's criteria and display it.
My Solution
I coded most of it myself, but used AI help for make_pw(), as I think I am fine without learning the random and string libraries in detail.
import logging
import random
import string
logging.basicConfig(level=logging.ERROR, format='%(asctime)s - %(levelname)s: %(message)s')
# Determines the length of the password
def get_length():
while True:
user_input = input('How many characters should the password have? ')
try:
user_number = int(user_input)
return user_number
except ValueError:
logging.error('Please answer with a number')
# Determines what characters are to be used in the password
def get_characters():
characters = {}
while True:
lower_case = input('Do you want to include lower case letters? ')
if lower_case == 'y' or lower_case == 'yes':
characters['lower_case'] = 1
break
elif lower_case == 'n' or lower_case == 'no':
characters['lower_case'] = 0
break
logging.error('Please answer with "yes" or "no"')
while True:
lower_case = input('Do you want to include upper case letters? ')
if lower_case == 'y' or lower_case == 'yes':
characters['upper_case'] = 1
break
elif lower_case == 'n' or lower_case == 'no':
characters['upper_case'] = 0
break
logging.error('Please answer with "yes" or "no"')
while True:
lower_case = input('Do you want to include digits? ')
if lower_case == 'y' or lower_case == 'yes':
characters['digits'] = 1
break
elif lower_case == 'n' or lower_case == 'no':
characters['digits'] = 0
break
logging.error('Please answer with "yes" or "no"')
while True:
lower_case = input('Do you want to include special characters? ')
if lower_case == 'y' or lower_case == 'yes':
characters['special_characters'] = 1
break
elif lower_case == 'n' or lower_case == 'no':
characters['special_characters'] = 0
break
logging.error('Please answer with "yes" or "no"')
return characters
# Generates the password based on input criteria
def make_pw(pw_length, pw_characters):
selected_characters = ''
if pw_characters.get('lower_case'):
selected_characters += string.ascii_lowercase
if pw_characters.get('upper_case'):
selected_characters += string.ascii_uppercase
if pw_characters.get('digits'):
selected_characters += string.digits
if pw_characters.get('special_characters'):
selected_characters += string.punctuation
if not selected_characters:
return "No characters selected."
password = ''.join(random.choice(selected_characters) for _ in range(pw_length))
return password
def main():
print('This program will generate a password for you. Please answer the following questions to customize your password.')
pw_length = get_length()
pw_characters = get_characters()
pw = make_pw(pw_length, pw_characters)
print(pw)
if __name__ == '__main__':
main()
