ds-class-intro

Welcome to the intro-level DS class, where we will learn about python basics and how to use python for exploratory data analysis. Hope you'll enjoy the class and learn something from it.

0. Get started -

If you can, try to go throug the following reading and set up your local environment before class:

• Anaconda set up
• Git introduction
• Set up you forked repo for commit and push + Homework submisstion instructions

Note: If you're getting the following error while cloning or pushing to GitHub, try to set up PAT following this instruction.

1. Python basics

You can run python in different settings, for example, you can use jupyter notebook for interactive exploration, use interpreter in command line by typing python in terminal (you'll see >>> prompt appear), or run python script in command line by python <your_script>.py. We will be using notebooks for the class as it's easy to follow with markdown and easy to interact with.
