Some coders possess laser-like code understanding skills. They look at a piece of source code, and the meaning pops immediately into their great minds. If you present them with a new code snippet, they’ll tell you in a few seconds what it does.
Since I’ve started to train this skill of rapid code understanding in 2017, I’ve made rapid progress towards being able to understand source code quickly. I’ve then created the Finxter.com app with my friends Lukas and Zohaib. Since then, hundreds of thousands of students have trained their code understanding skills by solving Python code puzzles on the Finxter web app.
Many of them have surpassed our skills by a wide margin in being able to see through source code quickly.
How did they do it? And how can you do the same?
The answer is simple: you must burn the basic code patterns into your brain. If you look at a word, you don’t realize the characters anymore. The word is a single piece of information. If a chess master looks at a chess position, he doesn’t see a dozen chess pieces. The whole chess position is a single piece of information.
You can burn those code patterns into your head by solving hundreds of code puzzles that make use of similar patterns but produce different outputs. This article gives you 100 code puzzles so that you can learn this mastery skill, too.
Action steps:
- Go over each code puzzle and take 10 seconds or so per puzzle.
- Guess the output of the code puzzle.
- Check your output against your guess.
- Repeat over and over again.
Ready? So let’s start rewiring your brain cells!
(But I warn you, don’t stop solving the code puzzles just because it gets boring. The puzzles are designed to be similar so that you can understand conditional code snippets 10x faster in all your future code projects. Push through your impulse to quit until you can see the source code in a second or two.)
10 Code Puzzles With Two Variables
Let’s start slowly. Can you solve these 10 code puzzles in less than 10 minutes?
# Puzzle 0

Let's go over the relevant parts of puzzle 0:
[1] Create and initialize 2 variables: a, b = False, True.
[2] Check condition (not b and not a and a). If it evaluates to True, move on the the next step [3]. Otherwise, enter step [5].
[3] Check condition (b). If it evaluates to True, print code to the shell. Otherwise, check condition (a and b). If it evaluates to True, print mastery to the shell. In any case, move on to the next step [4].
[4] Print python to the shell.
