Run Python codes in sequence, only run next code when the previous code runs successfully! 

In this video, we will look to automate our python code workflow.
We will design our process in a way that if you have multiple python codes you need to run, this will ensure that next code only runs if its previous dependant code ran successfully.
This becomes very important in situations where you have one big code divided into multiple dependant codes which utilise output of previous code.
