- Use a tab size of 4 spaces
- Eliminate trailing whitespace from files
- Use the PEP8 formatting style in Python files
- See for details on how to create and submit code changes.
- If you're doing a reformatting or cleanup to a file, and also making code changes to that same file, this should be done as two separate submissions (cleanup first, then changes).
- Unused or commented out code shouldn't be submitted, and any code that is no longer used or made obsolete should be removed.
