Python password generator

You may have already known how important it is to set a solid and secure password for each website. There is a bright future for authentication at least till we have passkeys. Until then we have to keep using passwords and maybe use a password manager to keep all those passwords safe.

Everyone in their life must have come to a situation where a website keeps on asking for a secure password and you can’t generate it. So here is the simple Python password generator

It will generate a random password, based on the characters you have specified. You can copy the python code below and keep on generating passwords.

How to use it ?

You just need to copy the script and paste it into a file on your server or windows machine. If you are using it as server then you can save this script as passwordgenerator.py then simply run the command below.

$ python3 passwordgenerator.py

You should get the output below.

Welcome to the PyPassword Generator!
How many characters would you like in your password?
25
 Your random password is: 159&2!I)Bg&%+u#2Zu1J&i7v7

So, just hover your mouse on the code and it will show you the button to copy code 🙂

# Password Generator Project
import random

# setting up the characters, numbers and symbols to choose from.
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 = ['!', '#', '$', '%', '&', '(', ')', '*', '+']

# Getting the input from user

print("Welcome to the PyPassword Generator!")

# Here we will ask user how much character he wants in his password.
characters = int(input("How many characters would you like in your password?\n"))

# Making sure that characters are between 1 and 50, else a user can enter a very large number and break down a server.
if characters > 50 or characters < 1:
    print("You need to choose number between 1 and 50")
    exit()

# Since we are choosing 3 different characters in password, I making sure that number is divisible 3.
# Hence, I will get the remainder and subtract it from the main number.

remainder = characters % 3
divisible_number = characters - remainder

# I am making sure that each character have similar numbers.

nr_letters = round((divisible_number / 3) + remainder)
nr_symbols = round(divisible_number / 3)
nr_numbers = round(divisible_number / 3)

# creating a list of characters using for loop.

password_list = []
for number in range(1, nr_letters + 1):
    password_list.append(random.choice(letters))

for number in range(1, nr_symbols + 1):
    password_list.append(random.choice(symbols))

for number in range(1, nr_numbers + 1):
    password_list.append(random.choice(numbers))

# at this point if you just print password_list will just print list
# below code will help in randomizing the password in the correct format in the list..

random.shuffle(password_list)

# setting the password as blank initially.
password = ""

# Coverting list into String
for char in password_list:
    password += char

# Printing Final Password
print(f" Your random password is: {password}")
