Article series: 5 Clean Coding Tips – 3. Take Advantage of the Formatting Tools.
This is the third of the article series “5 tips for clean coding” to follow as soon as you’ve made the first steps into your coding career, in this article series. Read the introduction here, to find out why it is important to write clean code if you missed it.
Unfortunately, no automatic formatting tool will correct the logic in your code, suggest meaningful names of your variables or comment the code for you. Yet. Gmail has lately started suggesting email titles based on email content. AI-powered variable naming can be next, who knows. Anyway, the visual level of the code is much easier to correct and there are tools that will do some of the code formatting on the visual level job for you. Some of them might be already existing in your IDE, you just need to look for them a bit, others need to be installed. One of the most popular formatting tools is pylint[i]. It is worth checking it out and learning to use it in an efficient way.
Beware that as convenient as it may seem to copy and paste your code into a quick online ‘beautifier’ it is not always a good idea. The online tools might store your code. If you are working on something that shouldn’t just freely float in the world wide web, stick to reliable tools like pylint, that will store the data within your working directory.
These tools can become very good friends of yours but also very annoying ones. They will not miss single whitespace and will not keep their mouth shut when your line length jumps from 79 to 80 characters. They will be shouting with an underscoring of some worrying color and/or exclamation marks. You will need to find your way to coexist and retain your sanity. It can be very distracting when you are in a working flow and warnings pop up all the time about formatting details that have nothing to do with what you are trying to solve. Sometimes, it might be better to turn those warnings off while you are in your most concentrated/creative phase of writing and turn them back on while the dust of your genius settles down a little bit. Usually the offer a lot of flexibility, regarding which warnings you want to be ignored and other features. The good thing is, they also teach you what are mistakes that you are making and after some time you will just stop making them in the first place.
