Pandas Brain Teasers »

This book contains 25 simple programs that will challenge your understanding of Pandas. Like any big project, the Pandas developers had to make some design decisions that at times seem surprising. This book uses these quirks as a teaching opportunity. By understanding the gaps in your knowledge, you'll become better at what you do. We geeks love puzzles and solving them. Avoid mistakes and impress your co-workers using these teasers.

Pandas Brain Teasers
September 16, 2020

On this day in 1946, the morning got off to a fairly unremarkable start for Frank Stenton of Larch, WI. Frank got dressed, walked the dog, ate steak and eggs, and headed into the office.

With coffee cup in hand, Frank sighed heavily as he considered the day ahead. Ten oppressive piles of paperwork, six overstuffed filing cabinets, and fifteen reports due by the end of the day...all in triplicate.

Frank didn't have a computer, let alone a machine that could learn anything. Nothing in Frank's life was high level, high performance, or dynamic. Frank didn't have access to exceptional learning resources. But you do.

Explore the ins and outs of a powerful Python package that's fine-tuned for data manipulation and analysis. Take advantage of today's technologies and modern methods of learning. If not for yourself, then do it for Frank.

Pandas Brain Teasers: Exercise Your Mind

Many of these brain teasers from author Miki Tebeka are from quizzes he's given at conferences and meetups. He found that people highly enjoy them and they tend to liven the room.

At the beginning of each chapter you'll see a short Python program with Pandas code in it. Miki motivates you to guess the output before going any further. Possible answers can be:

  • Syntax error
  • Exception
  • Some output (e.g. [1 2 3])

After guessing the output, Miki encourages you to run the code and see the output yourself, and then proceed to read the solution and the explanation. He has been teaching programming for many years this way and has found this course of action to be highly effective.

There's a lot of research showing that people who make mistakes during the learning process learn better than people who don't. If you use this approach at work when fixing bugs, you'll find you enjoy bug hunting more and become a better developer after each bug you fix.

This work was written and produced entirely by the author. We are proud to be distributing it.
