→Minimum Viable Product
== Minimum Viable Product ==
Once you have achieved the Milestones, you will have to do the following to get a minimum viable product:
* In your <code>if __name__ == '__main__'</code> block, you will have to check command line argumentscall the parse_command_args function. Experiment with print statements so that you understand how each option and argument are stored.
** If the user has entered more than one argument, or their argument isn't a valid directory, print an error message.
** If the user doesn't specify any target, use the current directory.
* Call <code>call_du_sub</code> with the target directory.
* Pass the return value from that function to <code>create_dir_dict</code>
