The excellent pre-commit framework (https://pre-commit.com/) has a hook for that in its official hook collection: https://github.com/pre-commit/pre-commit-hooks#detect-aws-cr...

This is what we use — https://github.com/pre-commit/pre-commit-hooks/blob/main/pre_commit_hooks/detect_private_key.py

Personally I do also add "end-of-file-fixer" and "trailing-whitespace" from the "https://github.com/pre-commit/pre-commit-hooks" repo. That cleans up and normalizes some files as well.

To get all your code into a consistent format the next step is to run a formatter. I recommend black, the well-known uncompromising code formatter, which is the most popular choice. Alternatives to black are autoflake, prettier and yapf, if you do not agree with blacks constraints.
