Using pycodestyle

We saw earlier that pycodestyle can be run from the command line to check a file for PEP 8 compliance. Sometimes it's useful to run this kind of check from a Python script.

In this exercise, you'll use pycodestyle's StyleGuide class to check multiple files for PEP 8 compliance. Both files accomplish the same task, but they differ greatly in formatting and readability. You can view the contents of the files by following their links below.

Exercise instructions

  • Import the pycodestyle package.
  • Create an instance of StyleGuide named style_checker.
  • There are two files that we'll be checking; they're named 'nay_pep8.py' and 'yay_pep8.py'. Pass a list containing these file names to our style_checker's check_files method.
  • print() the results of our style check to the console. Make sure to read the output!
