Wish to Be a Higher Information Scientist? Write Coding Tutorials! | by Conor O’Sullivan | Apr, 2023

Once I first began writing, I may hardly code. My little Python expertise got here from college initiatives. On the identical time, I believed I used to be an important author! Now trying again, I cringe at a few of my earlier articles.

This exhibits me that writing tutorials has improved each my technical and communication abilities. Finally, it has made me a greater knowledge scientist. I need to share my expertise and focus on some particular advantages. This consists of writing readable code and offering step one to writing about tough subjects.

Technical abilities are clearly necessary to builders and knowledge scientists. On the identical time, we work in fields which can be continuously altering. This implies we have to sustain with the most recent instruments. This may be tough and time-consuming so it takes an actual dedication to be taught repeatedly.

Writing has motivated me to constantly be taught new technical abilities and to develope a deep information on these subjects.

Writing has been an important motivator. Not solely can I be taught new issues however I can share these classes with the world. It’s addictive — having folks learn and work together along with your work. The will to constantly put up new articles has pushed me to constantly be taught new issues.

Not solely that however I discover writing is the finest strategy to be taught. Typically it’s solely after I’ve tried to elucidate one thing that I’ve realised I don’t really perceive it. On high of this, I all the time goal so as to add worth to a subject. Introducing novelty requires an excellent understanding. On this manner, writing has been a test on my information. It has pushed me to really perceive the technical ideas I write about.

Writing readable code

A associated talent is writing readable code. Good code ought to clarify itself. Equally, a tutorial based mostly on readable code is less complicated to write down. I spend much less time explaining what the code does and infrequently you do not have to elucidate it in any respect. I’ve discovered this profit extends to collaborating in trade.

Any idiot can write code that a pc can perceive. Good programmers write code that people can perceive.

— Martin Fowler

An instance comes from a latest article of mine — Utilizing SHAP to Debug a PyTorch Picture Regression Mannequin. Within the tutorial, I labored with SHAP values given in a 5-dimensional array. I wished to visualise this array utilizing one of many bundle’s capabilities. To do that, the array first wanted to be reordered. Initially, the code appeared like this:

# Reshape shap values for plotting
shap_numpy = [np.swapaxes(np.swapaxes(s, 1, -1), 1, 2) for s in shap_values]

The nested swapaxes capabilities weren’t enjoyable to elucidate. The TLDR is that the code transposed the array’s third dimension with the fifth dimension. I discovered myself writing a prolonged paragraph about how the code was doing this. So, as a substitute, I rewrote the code:

# Reshape shap values for plotting
shap_numpy = checklist(np.array(shap_values).transpose(0,1,3,4,2))

The transpose operate is extra intuitive and the code was simpler to elucidate. When writing code for tutorials, I’m all the time looking for examples like these. Readable code makes the writing course of smoother and the tutorial extra digestible.

I’ve discovered this talent significantly helpful when collaborating with different professionals. You may by no means get away from handovers and code critiques. Explaining code throughout these processes isn’t any completely different to explaining it in an internet tutorial. Finally, writing readable code means I’ve spent much less time explaining that code to colleagues.

Once I first began working, I shortly realised that non-technical abilities had been additionally essential. You not solely have to get outcomes but in addition clarify them and your course of. I needed to produce emails, displays or technical paperwork every day. There was no getting away from writing!

…historically, completely different folks comply with completely different paths of their careers―some are extra technical, others are extra inventive and communicative. An information scientist has to have each.

―Monica Rogati

Writing coding tutorials is nice follow for this. The extra I wrote the higher I used to be at speaking at work. Complicated evaluation turned simpler to elucidate and I needed to make clear my work much less. I shortly noticed the tangible advantages. But, this was simply the beginning.

Utilizing tutorials as a place to begin to your writing

In comparison with different articles, coding tutorials are simple to write down. There aren’t any deep ideas or nuanced arguments. You simply clarify the code. This implies they could be a strategy to get into harder writing.

Writing is one thing you want to practise to get good at. Tutorials helped me take my first steps. I began to experiment by including catchy tales to the directions and conclusions. Stumbling by way of these helped me to maneuver into various kinds of articles.

Taking extra assured strides, I moved onto items based mostly on my expertise as a knowledge scientist. These had been articles based mostly on extra summary ideas, my private expertise and emotions. I discovered these far tougher to write down than any coding tutorial. But, I’d not be at this level if not for these first tutorials.

Wanting again, there have been many advantages from writing coding tutorials. I’ve improved my technical information and realized to write down readable code. Writing tutorials has additionally introduced me to the purpose the place I really feel assured to write down about practically something. I haven’t even talked about the advantages for my popularity and the monetary compensation.

So, in case you are involved in writing, coding tutorials are an effective way to begin. If you’re battling concepts, you could discover this text helpful:
