Effective Pandas: Patterns for Data Manipulation (Treading on Python)

Product Information

The Python world (which is arguable 10-100X bigger than the R world) has converged on the Pandas API. Most of the reporting from book sales you hear about is probably from the top end, so don't be disappointed if you don't achieve similar results.

Here is a snapshot of a (small) subset of all of my Coding, Data Science and Machine Learning books.

I have reviews from beginners and experience alike that this is changing how they think about Pandas. The course is served on the Podia platform, which has a decent interface for presenting the course materials and a video player with standard controls.

One of the best investments that you can make when becoming a data scientist is to become a Pandas expert, and there is no better book than Harrison’s to help you get there.

The result is an highly-opinionated book that teaches best practices for working with columns, manipulating tables, summarization through grouping, pivoting, and cross-tabulation, plotting, and focusing on writing clean code that your future self (and colleagues) will appreciate and understand. At the end of each chapter, Matt asks you to reinforce what you learned by practicing on a dataset of your choice. If you haven't read Matt Harrison's book and use Pandas, chances are you're like that Chad at the picnic or camping trip that pulls out his guitar to strum along the same basic chords for an hour straight. Truly, it is one of the most straightforward and powerful data manipulation libraries, yet, because it is so easy to use, no one really spends much time trying to understand the best, most pythonic way to employ the library to its full extent. And you will see how I encounter failure and deal with it-highly recommended after you finish the labs!So you come across many of the annoying, hairy, and ugly issues and are shown how to deal with them. After debugging your results and pulling out a bit of hair, you think, "perhaps there is a better way? Tips and insights on things like effectively chaining pandas methods, improving memory usage through manipulation of data types, making sure that appropriate constructs are used for accessing intermediate data frames in chained sequences (see notes on lambda functions in ch 10 and on the differences btw . In reference to Alexey’s comment below about dplyr, I have barely used it, but many of my teammates use it, and they have shown me the basics. Since then, Pandas (with all of its warts and inconsistencies) has taken the world by storm (for better or worse).

Getting started with the basics of working with data in Pandas is not too difficult, but moving beyond those basics to extract the most value from all that functionality takes time, effort and good learning resources. The book is full of useful information and practical knowledge for the daily use of pandas, and also contains interesting focus on some external features such as Cython, CatBoost or sparklines. I skimmed through several chapters because I’m reasonably familiar with pandas, but I’d recommend the book to anyone who uses pandas a lot. What I mean is that most authors try to get their word out, teachers go further and try to make the ideas get in readers' brains.

While all tools have their advantages and disadvantages, pandas are probably the most efficient out of all of them.
