Password Generator | Python
My next challenge is a random password generator! This program prompts the user for how many alpha-characters, symbols, and numbers should be included and then randomly generates a string of text based on those parameters for use as a password. This project uses the imported ‘random’ module as well as ‘lists’ and ‘for loops’. Let’s take a look at some of the code:
First, I import the ‘random’ module for use later in randomly generating an index for our lists. Three lists are then declared, each holding letters, numbers, and symbols respectively. A fourth list titled ‘password’ is declared but left blank for use later in the code.
Next, four print statement are presented via the terminal. Print statements one and three print a row of x’s with the instructions being printed between them via print statement two. Print statement four (‘\n’) places a blank line before the next three user prompts.
These user input prompts are presented one at a time, with the user’s input being stored in variables ‘user_letters’, ‘user_symbols’, and ‘user_numbers’ respectively. All user inputs are wrapped in the int() function, to convert them from strings to integers. This enables easier useability later as indexes for our lists.
A ‘for loop’ using the range() function then iterates from one to the value stored in ‘user_letters’ plus one. For each iteration, the program appends a random selection from ‘letter_bank’ to the ‘password’ list. This same process is repeated twice more using the ‘user_symbols’ variable and ‘symbol_bank’ list and then the ‘user_numbers’ variable and ‘number_bank’ list.
The program then declares an empty variable called ‘final_password’. One last ‘for loop’ iterates over each character in the ‘password’ list and adds it to the ‘final_password’ variable. This converts the randomly generated password from individual characters in a list to a cohesive string.
Finally, the program prints one last statement to the terminal with the generated password. In typical fashion, I am using a string-literal which replaces the variable name ‘final_password’ with the value (the generated password) held inside.
