WHY LEARN CODING WITH DR CODIE:
If you want to know how to learn python then these python programming tutorials are for you. Hi, my name is Dr Codie and I have helped many students to learn python, Scratch, SQL and other programming languages. In these videos you see how to learn python using your existing knowledge and gain some tips for learning python. Codie means ‘helpful person’ and we want to help you not just learn python programming but to enjoy learning python. We start with python tutorials for beginners and then move to tutorials for more advanced learning. The videos teach python 3.
In my experience, success being a python coder comes down to getting the fundamentals right. You can then move onto advanced programming concepts and skills. You will understand how to do simple coding tasks and then we will show you the simple methods of putting lines or blocks of code together using this knowledge. Practice is essential for your skills to grow but again do not fear we will help you practice as well.
Learn to understand the logic and design aspects needed to become a good programmer, let us help you practice to keep improving and don’t forget the bonus of seeing first hand how to build the code and possible stumbling blocks when we explain the answers to the tasks set within the tutorial. You do not need to watch the whole video but if you do you will improve as a python coder!

Confusion Matrix on the comment. Mr Shelton online is American and your fly is down is an expression unrelated to this. So it doesn't translate. Sorry.
