Intro
My Python is like my Spanglish, I can just about read it and writing it is even worse!
So I’ve just started the below linked course on Udemy. Like the instructor I believe that the best way to learn is to be hands on
MAC Address Changer
The mini project the course starts off with is a MAC address changer.
Within it you learn the following
- Print statements
- Importing modules
- Using subprocess.call from module subprocess to initiate system commands.
- Parsing arguments.
- Defining functions.
- Creating statements.
