Is much of your time spent doing tedious tasks such as cleaning dirty data, accounting for lost data, and preparing data to be used by others? If so, then having the right tools makes a critical difference, and will be a great investment as you grow your data science expertise.

Next, you will cement your knowledge of the basic concepts that the rest of the book relies on: file formats, data types, and character encodings.
