This composite action runs flake8 with reviewdog on pull requests to lint to lint python source files while creating annotations. It does this by installing the Python flake8 package in an environment with a Python interpreter and executes flake8 stylistic and logical linting of Python source files. Following reviewdog is used to parse the bash output into GitHub annotations. This (composite) action is meant to be run inside an existing workflow and therefore, does not install python or set up a python environment.

In it's simplest form this action can be used to annotate the changes that are suggested by the flake8 linter.
