pre-commit is a plugin that runs automatically on git events. If you want you can open a PR to include the steps like so:

Pre-commit plugin

To forget about coding style and let pre-commit fix your flake8/isort/black issue.

• Install pre-commit: $ python -m pip install pre-commit
• And then: $ pre-commit install

That's it!

that seems to look good, almost 70% percent of pull request I see fails pre-commit which was hard to fix manually until i came to know we can use this locally to make changes

hey , @dhruvmanila i would Love to work on this issue .
Pls assign this issue to me .

Well @Joe-Sin7h, You can start working and link this issue in your PR. No need to get assigned

Hello, I have made the necessary changes in CONTRIBUTING.md, and I am getting the following error when I try to commit the changes:

Could you please help me out?

Sure, You should try the steps yourself (Warning: they are steps for you only, complete steps have been mentioned above):

• pip install pre-commit
• pre-commit run -a

Also, retry the whole procedure of commiting, and then upload the C:\Users\Ashish Papanai\.cache\pre-commit\pre-commit.log to this place

Hello @xcodz-dot The last pre-commit test i.e. Validate filenames is failing with the following error:

It seems something is trying to open the python executable

I recommend for you to try the official python setup instead of windows app.
https://www.python.org

Tried everything, The final step is still failing. @xcodz-dot

Try running this command in root of repo instead of old one, also post your command line and log again after this:

• pre-commit clean
• pre-commit gc
• pre-commit run -a -v --show-diff-on-failure

It is the root of the repository. i.e. E:/Git Contributions/Python

Ok try the commands

@xcodz-dot The following lines are from cmd after running the commands mentioned by you:

E:\Git Contributions\Python>pre-commit clean
Cleaned C:\Users\Ashish Papanai\.cache\pre-commit.

E:\Git Contributions\Python>pre-commit gc

I can't help much cause the issue is with internal working

@xcodz-dot I tried to commit using WSL, any idea that why is it looking for shebang and how to fix that?

ashishpapanai@ashishpapanai:/mnt/e/Git Contributions/Python$ chmod -x CONTRIBUTING.md
ashishpapanai@ashishpapanai:/mnt/e/Git Contributions/Python$ git commit -m "Fixes Issue#3887 Guiding people using contibuting.md"
Check that executables have shebangs.....................................Failed
- hook id: check-executables-have-shebangs
- exit code: 1

CONTRIBUTING.md: marked executable but has no (or invalid) shebang!
  If it isn't supposed to be executable, try: `chmod -x CONTRIBUTING.md`
  If it is supposed to be executable, double-check its shebang.

Check Yaml...........................................(no files to check)Skipped
Fix End of Files.....................................(no files to check)Skipped
Trim Trailing Whitespace.................................................Passed
Fix requirements.txt.................................(no files to check)Skipped
black................................................(no files to check)Skipped
isort................................................(no files to check)Skipped
flake8...............................................(no files to check)Skipped
codespell................................................................Passed
Validate filenames.......................................................Passed

I tried to remove the executable permissions of contributing.md by chmod -x CONTRIBUTING.md But it didn't help.

how about trying pre-commit run -a here

Also, which editor are you using?

You can try raising this issue in pre-commit repo, they might help you out
