Writing code that any programmer who read can understand is a for software developers. The fact is: only 20% of the programmers have the ability. must-have skill “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” — Martin Fowler When I started caring about code readability I noticed that my code started to be: easier to maintain easier to refactor reusable consistent The Book is the clean coder programmer bible. This book talks about code, behaviour, automated tests and so on. Robert "Uncle Bob" Martin's "Clean Code: A Handbook of Agile Software Craftsmanship" Let's get practical! Writing meaningful names. One of chapters talks about meaningful naming. In this story, you are going to be the code reader.

Why? “calc” is an : don't! abbreviation Functions do something. It must be named with a . verb Even I rename "calc" to "calculate", it still be vague. We need to improve the by giving the function name more meaning. semantics This function divides two numbers. "divide" is a good name for it. def divide(n1, n2)return n1 / n2end result = divide(1, 2) We still have problems with it. "n1" and "n2", the parameters, are not semantic. What if we call them "dividend" and "divisor"? The same thing to the "result" variable. It should be called something like "quotient". def divide(dividend, divisor)return dividend / divisorend quotient = divide(1, 2) Much more semantic!
