PEP8: Python Style Guide
PEP8 is a style guide for Python code that outlines recommendations for formatting, naming conventions, programming practices, etc. to improve Python code readability and consistency.
What is PEP8?
PEP8 is a set of coding conventions and style guidelines for writing more readable and consistent Python code. It covers topics like:
- Indentation - Use 4 spaces for each indentation level
- Maximum line length - Limit lines to 79 characters
- Blank lines - Surround top-level function definitions with two blank lines
- Imports - Imports should be on separate lines
- Whitespace - Don't use extraneous whitespace inside parentheses, brackets, etc.
- Naming conventions - Use snake_case for function names, variables, etc.
- Programming practices - Avoid extraneous comparisons, nested blocks, unnecessary pass statements
Following the PEP8 guidelines makes Python code easier to read and understand for other developers. It enables writing clean, standardised code that conforms to the wider Python community's expectations. Many linters and IDEs can check PEP8 compliance automatically to help enforce these guidelines.
