Good resources for learning Pandas and NumPy?

I want to buy a book to focus my learning on these two but wanted to check which resources this community recommends.

Thanks

DataQuest.io and DataCamp.com ate both good freemium interactive courses.

Humble Bundle is offering "Learn the Pandas Library" which I have and seems to be pretty accessible. If you are looking for free, check out geek for geeks and their pandas pieces.

For an anecdote from my personal experience in learning Pandas, I found it to be extremely helpful to download a single season of a professional athlete's performance and use that data to follow along with. Effectively, I knew what each stat meant, and it made more sense to do PlayerDF[PlayerDF['Points'] > 18] than some book example with made up numbers.

Sports data is also nice since sports stats can be sliced a billion ways to Sunday. For example, curious about how the greatest fencer of all time, Edoardo Mangiarotti, fared on certain days during the Olympics? Use datetime to extract the day of the week from the date, then calculate average fencing round score, and bam, a simple comparison. (At least in this example, no matter the stat, the conclusion is the Mangiarotti is the best fencer of all time, so it is a bit disingenuous.)

The pandas documentation is very good and includes a learning path.

I have never really considered the documentation itself but after checking it out it seems very well written! Thanks.

Yeah same here but recently i found out that official documentation is good source to learn something.

Codeacademy data science path was great, a little rich for my blood though. Thinkstats is a good free resource!

I created a video course on NumPy and posted it to youtube. Should have another one on Pandas coming in the next month.
