Python Course: Files

In this project, I worked with files using Python. This was part of the learning module on files, which is for the Python course I am taking.

import csv

#Retrieve usernames from a csv file
compromised_users = []
with open('passwords.csv') as password_file:
  password_csv = csv.DictReader(password_file, delimiter=',')
  for row in password_csv:
    password_row = row
    compromised_users.append(password_row['Username'])

#write usernames to a new file
with open('compromised_users.txt', 'w') as compromised_user_file:
  for user in compromised_users:
    compromised_user_file.write(user + "\n")

import json

#create a JSON file to notify the boss
with open('boss_message.json', 'w') as boss_message:
  boss_message_dict = {"recipient": "The Boss", "message": "Mission Success"}
  json.dump(boss_message_dict, boss_message)

#remove the original passwords file and replace with rival hacker's signature.
with open("new_passwords.csv", 'w') as new_passwords_obj:
  slash_null_sig = """ _  _     ___   __  ____
