Readability is a primary focus for Python developers, in both project and code documentation. Following some simple best practices can save both you and others a lot of time. A README file at the root directory should give general information to both users and maintainers of a project.

First, you'll learn about Pandas and its DataFrame construct. This is the most common way to work with data in the Python Data Science world.
