How do grandmasters of chess become that way? They study thousands of chess positions. They look at a chess position, commit to a solution, and compare it against the "gold standard" -- the best move in a given position.

This book is the chess grandmaster way of learning Python. It offers you 127 unique and brand-new Python puzzles. Every puzzle points to gaps in your knowledge, challenges you to guess a solution, and then explains potential solutions, in an easy-to-understand manner.

An easy, fun, and extremely effective way of learning Python -- day after day -- in your COFFEE BREAK PYTHON!

Burn 127 new Python patterns into your brain and rewire your synapses.

Here's what research says about puzzle-based learning:

"Students who were quizzed after studying a short text could recall significantly more information than students who were asked to reread it"

-- Karpicke, 2007, Elsevier Journal of Memory and Language

Practice testing is scientifically proven to generate up to 44% better learning retention and efficiency.

Simply put: quizzes and puzzles work! More than 100,000 Finxters and thousands of "Coffee Break Python" book customers have successfully improved their skills with code puzzles.

Learning does not happen in a linear and orderly manner. It's a probabilistic, chaotic, and iterative process of creating knowledge gaps in your brain -- and filling them with just the right information you need.

That's the premise of the "Coffee Break Python" textbook series.

Here's how you will change by reading this book:

Each Python puzzle in the book is standalone, which means that you can solve each puzzle independently.

You get 127 Python code puzzles as Python scripts (Jupyter Notebook) -- one for each Python puzzle in the eBook.

Download the files, play with them, explore them on your own computer.

This helps you learn Python even faster!
