- [yapf](https://github.com/google/yapf) - configurable formatter from Google | [Online demo](https://yapf.now.sh/)



## Linters

- [flake8](https://gitlab.com/pycqa/flake8) - glues together pycodestyle, pyflakes, mccabe, and third-party plugins to check the style and quality of code 

- [mccabe](https://github.com/PyCQA/mccabe) - McCabe complexity checker

- [pycodestyle](https://github.com/PyCQA/pycodestyle) - former `pep8`. Check your Python code against some of the style conventions in PEP 8.

- [pydocstyle](https://github.com/PyCQA/pydocstyle) - docstring style checker 

- [pyflakes](https://github.com/PyCQA/pyflakes) - A simple program which checks Python source files for errors.

- [pylint](https://github.com/PyCQA/pylint) - code analysis tool which looks for programming errors, helps enforcing a coding standard, sniffs for code smells and offers simple refactoring suggestions.



## Import sorters

- [isort](https://github.com/timothycrosley/isort) - sort imports alphabetically, and automatically separated into sections

- [reorder_python_imports](https://github.com/asottile/reorder_python_imports) - reordering python imports
