wtf is pep8?

The pep8 project is a tool that checks your Python code for style issues. It looks at your code and flags things like misplaced whitespace, lines that are too long, missing blank lines, or deprecated ways of writing certain statements. The point is to help you write code that follows Python's official style conventions, known as PEP 8, so your code looks consistent and readable to other Python developers. You run it from the command line, pointing it at a Python file or directory. It scans the code and prints out a list of issues, each with a file name, line number, column position, and a short description of the problem. You can ask it to show the exact offending line of source code with a pointer to where the issue is, or even display the relevant rule from the style guide. You can also run it in a statistics mode that counts how many times each type of error appears, which is handy for getting a sense of how much cleanup a codebase needs. This is useful for anyone writing Python who wants their code to meet community standards, whether you are a beginner learning good habits or a team lead trying to keep a shared codebase tidy. For example, if you inherit an older project and want to know how far it drifts from convention, you can run the tool across the whole thing and get a report. Many text editors can also parse its output to let you jump straight to each flagged location. What makes the project notable is its simplicity. The entire checker lives in a single Python file with no external dependencies, so you can drop it into almost any environment without installing a pile of libraries. It also has a plugin architecture, meaning you can add your own custom checks without much effort, and it ships with a test suite to verify everything works.
