Little time to learn Python?

Python puzzles help you to learn faster, smarter, and better. This book offers 50 educative code puzzles, 10 tips for efficient learning, 5 Python cheat sheets, and 1 accurate way to measure your coding skills. 13,000 Python students have already improved their coding skills on our puzzle-based learning academy Finxter.com.

"I very much enjoy your Finxter.com website because it has some real meat to the problems. Thank you so much for doing this project! I love it!"—David C.

"Your site is awesome."—Victor A.

"I found Finxter.com an excellent tool to brush up on my Python skills."—Jesper R.

As you work through Coffee Break Python, your Python expertise will grow—one coffee at a time. You will train wildly important Python topics such as

- Arithmetic operations: integer & float division, and modular arithmetic;

- Language elements: branching, loops, keywords, and functions;

- Data structures: integer, float, string, list, set, dictionary, and graph;

- Sequence operators: indexing, concatenation, slicing, and built-in functions;

- Function *arguments: default *, arbitrary *, unpacking *, keyword *;

- Set operations: lambda, filter, map, and intersection functions; and

- Algorithms: recursion, Fibonacci, Bsearch, sorting, guess & check, and graph traversal.

As a bonus, you will track your individual Python coding skill level throughout the book.

To get the most out of this book, you should be slightly beyond beginner-level in Python—e.g., you have already experience with another programming language, are a professional engineer, or a student.

So how do you spend your Coffee Break? Python!

Puzzle-based Learning Python

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:

~~~

# Here’s one example puzzle:

my_list = [1, 1, 1, 1]

my_list[1::2] = [2, 3]

print(my_list)

# What’s the output of this code snippet?

~~~

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

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 already 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.

What will you get out of the book?

• Improve your level of deep Python code understanding.
• Surprise your peers with your newly acquired code speed reading skills.
• Enjoy the small daily doses of intellectual challenges. A Finxter once called it "Sudoku for coders"! ;)
• Improve your brain's working memory by hammering down the most important concepts.
• Learn all the basic Python syntax elements.
• Discover your own skill level by tracking your puzzle-solving performance.
• Compare your skill level against other coders: are you a grandmaster of code?
