According to PEP-8 recommendations, how should you indent your code?

• A. 2 spaces per level
• B. 4 spaces per level
• C. 1 tab per level
• D. 8 spaces per level

Answer: (B)

PEP 8, which is the style guide for Python code, recommends using 4 spaces per indentation level. This recommendation aims to enhance the readability of the code, as consistent use of spaces helps in visually distinguishing blocks of code. Using 4 spaces is considered a good compromise between clarity and compactness.

When following PEP 8 guidelines, it is crucial to maintain consistent indentation throughout your codebase. This standardization not only makes it easier for you to read your code but also ensures that others who might read or collaborate on your code will have an easier time understanding its structure.

In contrast to the other options, using 2 spaces or tabs for indentation might lead to confusion or inconsistency in some codebases, particularly since tab-width settings can vary between different editors, potentially leading to misaligned code. Additionally, the use of 8 spaces per level is generally considered excessive and could make the code unnecessarily wide, making it less readable, especially on smaller screens or within limited-view setups. Hence, 4 spaces per level is the best practice as outlined in PEP 8.
