Adding pre-commit (package) to git repo of your python projects

Git pre commits  are quite useful to analyze  the code before you make a commit and pre-commit makes it quite easy to mange these hooks and rules to run via these hooks.

• Install pre-commit, pip install pre-commit ## detailed instruction  on it's website pre-commit
• Run pre-commit install ## Usage instruction  on it's website pre-commit
• Create .pre-commit-config.yaml file in your project root
• I have added it to  behave-selenium, check it out

pre-commit install will install pre-commit into your git hooks, now on words it will be run on every commit. 

Every time you clone a  project running pre-commit install should always be the first thing you do.

The first time pre-commit runs on a file it will automatically download, install, and run the hook. Note that running a hook for the first time may be slow. 

• To Run all pre-commit manually on all file type pre-commit run --all-files
• To run specific hook (via the id in .pre-commit-config.yaml) on specific file(s) pre-commit run autopep8-wrapper --files features/steps/google_steps.py

We can also run all the pre commit hook as a CI step e.g. pre-commit run --all-files 

Individual tools can configure in accordance to according to there configuration. For example flake8 can be configured by adding a setup.cfg file
