The book provides really good insights on some of the most popular tools for data science, addressing issues like dealing with outliers, preprocessing data, showing your data in meaninful and easy to understand ways, dealing with different scenarios presented in real world problems demanding knowing skills in the usage of data.
There were a few typos here and there, and I consider a few more detail could had went in some of the examples.
Other than that, it's an eady to read pick for anyone knowing some basic data science stuff and trying to learn about the different situations one might have to confront.
