 - **python-mode**: use `run_filters_pyio`  function in python.
 
-For an example, `md2md_enhance_equation_filter` in [enhance_equation.py](https://github.com/Zhaopudark/pandoc-filter/blob/main/src/pandoc_filter/filters/md2md/enhance_equation.py) is a filter function as [panflute-user-guide ](http://scorreia.com/software/panflute/guide.html).
