5 Simple Tips to Writing CLEAN Python Code

Use meaningful variable names: Instead of using generic variable names like a, b, c, use names that are descriptive of the data they hold. This makes it easier for others (and yourself) to read and understand your code. For example, instead of x = 10, use num_of_students = 10.

Write short and concise functions: A good function should do one thing and do it well. If your function is too long, it can be hard to understand what it does. Splitting it into smaller functions with descriptive names can make your code more readable and easier to maintain.

Use white space properly: Use whitespace to separate code blocks and make your code easier to read. Avoid using unnecessary whitespace, like multiple blank lines between functions or statements. PEP 8, the official Python style guide, recommends using 4 spaces for indentation.

Follow the DRY (Don’t Repeat Yourself) principle: Avoid duplicating code by extracting repeated code into functions or variables. This makes your code more concise, easier to read, and reduces the likelihood of errors.

Comment your code: Write comments that explain why you wrote the code, not just what it does. Use comments to clarify any confusing sections of code, and add context to your code. This can help you and other developers understand your code more easily, and make it easier to maintain in the future.
