Rather than writing the code to simulate the login attempts every time, we can package this up in a script that we can easily run from the command line. The Python standard library has the argparse module (https://docs.python.org/3/library/argparse.html), which allows us to specify arguments to our script that can be supplied from the command line. Let's take a look at the simulate.py file to see how to do this.

We start with our imports:

In order to provide status updates when using this from the command line, we are going to set up logging messages using the standard library's logging module (https://docs.python.org/3/library/logging.html ...
