Vivek is very knowledgeable and good at explaining python features and best practices to beginners. He has been helping me to set up my folders and virtual environment, and talking through each line of code to explain the functionality. As a complete beginner, I was attempting to replicate data analysis from a github repository, and was able to do it after spending less than 2 hours talking to him. A great tutor!
