The Kata


I’m learning python for some time now. I’ve made myself familiar with the syntax and then started looking into other ways to increase my knowledge about language and learn its quirks. I’ve found a very nice site that allows me to practice basics and strengthen different kind of muscles that I’m using in my day job - adventofcode.


The idea behind adventofcode is very simple - during advent time before Christmas everyday you get a task to solve. I’m not into the theme too much as it’s August now :) What I care about are problems that can be solved. At work, I’m facing different kind of challenges and those in adventofcode are more like sudoku and allow to learn the language more deeply and learn about its features.

One of the problems to solve recently was based on solving the maze (more than one actually but they usually differ in some ways). I’m not going to show my ugly python code (you are opening it on your responsibility). As you’ll find many sites on the internet that will show you how to implement BFS or maybe event how to solve the maze. I just wanted to point out something different so bear with me for a moment.

It might sound lame but I’ve never had a chance to write maze solving program. I’ve struggled with it a bit as those are not problems I’m accustomed to and once I got it working I was really satisfied.


If you look at the maze problem that’s a graph in which you have to find the shortest (or existing) path to exit (some node). So I had a chance to refresh my knowledge on this topic (because who remembers what one has learned years ago…) and I’ve (re)discovered a couple of graph traversing algorithms and then implemented one, then struggled a bit on how measure traveled distance and finally got this thing working.

The point

By doing those puzzles I’m getting:

  • Knowledge refresher (some problems are really interesting and it takes some time until you figure out what to ask google for :))

  • Algorithm implementation practice with some tweaking (no copy-paste rule - you must understand what’s going on)

  • Good brainteaser (if you are into that)

  • Language programming practice (I think it’s a good way of getting familiar with the syntax and possibilities of the language you’ve started practicing)

  • Satisfaction of solving problems that do not exist (that’s the winner I think) ;)

Maybe you’ve heard about programming katas. In the beginning, I didn’t get the idea but now I understand it when I’ve found my way of implementing it. If you’ll find the right problems to solve and some time to do them you’ll find it "entertaining and rewarding" (some people like to solve sudoku or crosswords). And you can get more of it as you’ll start working the muscle and practicing something different that you do in your day to day job. For me it clicked when I’ve found interesting problems to solve and my way of practicing it - one puzzle a week and I should be satisfied with the solution (rewrite is ok).


I think that solving those challenges made me a bit better at what I do (at least I’m feeling ok-ish with python and know and understand BFS algorithm and a couple of others which I already forgot ;)). I’ve also found a pretty solid way of strengthening my problem-solving muscle and practicing new programming language at the same time while I’m getting some "fun" when doing those things. I recommend you try it and see for yourself, who knows maybe you’ll find some possibilities of growth in this as well.
