What are some examples of PEP 8 style guidelines in Python?

PEP 8 is the style guide for Python code. Here are some key examples:

1. Indentation: Use 4 spaces per indentation level.
2. Line Length: Limit lines to 79 characters.
3. Blank Lines: Use blank lines to separate functions and classes.
4. Imports: Imports should usually be on separate lines.
5. Naming Conventions: Use lowercase with underscores for function names.

Can you give me a specific code example that follows PEP 8?

Sure! Here's a simple example:

def my_function(param_one, param_two):
    """This function does something useful."""
    result = param_one + param_two
    return result

This code follows PEP 8 guidelines with proper indentation, naming conventions, and a docstring.

What about comments? How should I write them according to PEP 8?

PEP 8 recommends using comments to explain code. Here are some tips:

• Use inline comments sparingly and only when necessary.
• Block comments generally apply to some (or all) code that follows them and are indented to the same level as that code.
• Use # followed by a space for comments.

Are there any tools to help check PEP 8 compliance?

Yes, there are several tools available:

• Pylint: A comprehensive tool that checks for errors and enforces a coding standard.
• Flake8: A tool that checks the style guide enforcement.
• Black: An opinionated code formatter that automatically formats your code to comply with PEP 8.
