README for User Authentication Code This Python code is a simple user authentication program that reads a CSV file named datos.csv to verify if the username provided by the user is in the list of valid users.
Dependencies// The code uses Python's standard library csv and the datetime class from the datetime library.
Usage// To use the code, make sure to have a CSV file named datos.csv with a list of valid usernames. The code will prompt the user to input a username. If the username entered is not in the list, the code will display "Access Denied" and prompt for the username to be entered again. If the username is in the list, the code will display "Access Granted".
In addition, the code adds a new empty user to the end of the list and replaces all usernames in the list with asterisks. It then writes the updated list to the datos.csv file. It also writes the username and the current time to a CSV file named Hora.csv.
