9 of 9 people found the following review helpful. I don't know why there are so many 5-star reviews. By FeFiFoFu I purchased Learning Pandas based on the steady stream of 5-star reviews here on Amazon, but the reviews completely let me down on this one. I've only started learning Pandas in the past week or so and I find this book way too basic, with little detail. Honestly, at around the page 250 of 480, all you've done is imported data from a CSV file, print rows or columns to screen, deleted and added a column or row. At this point, you still haven't any aggregated or summarized any data yet. In addition, the items covered to that point were not covered in depth.I did check the Table of Contents before purchasing, but what threw me off were all the 5-star reviews from people who claim it's their job using scientific libraries, or they've been using pandas for awhile. Because of these reviews and the length of the chapters, I though there would be some "comprehensive insights" or "powerful data manipulations" as some reviewer say... some real meat that would be conceptual, comprehensive and/or practical in these pages. But nope, you learn a useless function called "twiceprice" which takes a column of stock prices and multiplies it by 2. What a useless, un-insightful, un-practical example. Most of the examples don't use real life data, he just uses series of a,b,c and 1,2,3.

Practical examples and useful reference content By Natester I've been working with the pandas library for a while but had been looking for a text to help navigate the rich feature set of the pandas library. I purchased this book as soon as it became available and I'm quite satisfied with the content.I skipped the first few chapters, but if you are new to Python and using Python packages, do be sure to go through the content.The next couple of chapters discuss the inner workings of pandas DataFrame and Series. Worth going through as it provides a foundation for the remainder of the book's examples.Around chapter 6 is where the application examples dig in and they are quite useful. I've referred to many of these examples. They include reading and writing data with different data sources, slicing and dicing data and running stats on your data.Examples towards the end of the book get progressively sophisticated with shaping data. I didn't read everything in those chapters, but towards the end of the book are some chapters on data visualization and working with time series data. Definitely a "must" if you are looking to make use of pandas in your data analysis work.I keep this ebook in my reference collection and refer to it when in need to figure out how to solve a data issue where pandas might be a good fit. A helpful book in the Python + data space.
3 of 3 people found the following review helpful. getting to know indexes and look-ups By Ken B. Pierce Jr. I've been learning pandas for a few months and really looked forward to a new reference. While I've read most of Kinney's book (he started the package) I've found the concepts around indexing and the multiple ways to access data a bit difficult, especially coming from an R/dataframe background. The series and dataframe chapters in Heydt's book clarified a number of things for me about the use of .loc, .loc[] and .ix. I especially got confused with Panda's auto-indexing feature and how if you have an integer index and pass myData[2] you might get the row with the index label 2 or you might get the third row if Pandas added an auto-incrementing index (or your integer index is sorted and complete). I liked the explanation in this book. Pandas is really powerful and while I'll continue to use R/dplyr/etc for many tasks, I'm increasingly finding Pandas and python super useful. Note for GIS applications using Arc, it is relatively easy to move from a filegeodatabase to a numpy array to Pandas and back. This has been great for doing a lot of calculations with really big feature sets.
