But maybe you're starting to feel overwhelmed. Here's help to ease your journey. Here are a few creative hobbies that are proven to help in this way. Read More — it looks easier than it actually is. Well, because the benefits are worth it: Problems become easier to solve.
Once you start thinking in clean code, your approach to problem-solving changes. Instead of brute forcing solutions, your algorithms and software design become more elegant and intentional.
Less time is wasted on maintenance. Clean code is easier to read and understand, so you spend less time trying to figure out what certain segments actually do and more time on fixing, revising, extending, etc.
Ideas are more clearly communicated. Use Descriptive Names What are variables, classes, and functions? There are many ways to answer that, but when you really think about it, those things are nothing more than the interface between a programmer and the underlying logic of an application.
On the other hand, the meaning of a variable like distanceBetweenXY is instantly recognizable. The same is true for classes and functions.
If you have, then you know how much of a pain it can be to browse, understand, and edit. Comments can help but only to a limited degree. Every function should aim to do one single thing and every class should aim to represent one particular concept.
This is a simplification of course, but when in doubt, simpler is cleaner. Delete Unnecessary Code This bad habit is one that I still struggle with from time to time.
It usually happens like this: I want to fix or optimize a chunk of code so I comment it out and do a rewrite just below it — and even though it works, I keep the old code there just in case.
Perlis Over time, I accumulate a whole lot of commented-out blocks of code that are no longer needed yet clutter up my source files.
Cleaner code awaits you. Sure, it takes up less space on the screen, but is it actually easier to understand? But most of the time?
Kernighan I think programmers love clever code because it feels like a solved puzzle or riddle. But to write clean code, you need to leave your ego at the door.
What Makes a Good Programming Tutorial? Not all programming tutorials are made equal. Some benefit you and others end up wasting your time. Here's what to look for in a quality programming tutorial. Read Morebut one of the downsides is that newbies end up picking up a wide variety of conflicting habits, especially as they pertain to coding style.
If you want braces on their own lines, go for it.A very useful Python package is the csv, a module which helps the Python programmer with prebuiltin utilities that can deal with comma-separated values.

Developers all over the world like it due to its peculiarities which make Python stand out from other programming languages. It encourages programmers to program without boilerplate (prepared) code. The simplest directive in Python is the "print" directive - it simply prints out a line (and also includes a newline, unlike in C).
There are two major Python versions, Python 2 and Python 3. Python 2 and 3 are quite different.
