DISCLAIMERS

1. Please note that this is not a course for beginners. This course assumes that you have a background in software engineering and are proficient in Python.
   I will be using Pycharm IDE but you can use any editor you’d like since we only use basic feature of the IDE like debugging and running scripts.

2. The first project of the course (Ice-Breaker) requires usage of 3rd party APIs-
   ProxyURL, SerpAPI, Twitter API  which are generally paid services.
   All of those 3rd parties have a free tier we will use to create stub responses development and testing.
