Thanks. Found how to suppress it indeed. Reference for future generations: https://www.jetbrains.com/help/pycharm/suppressing-inspections.html
In this case it'll look like this:
# noinspection PyArgumentList data = PData(dataname=df)For code/output blocks: Use ``` (aka backtick or grave accent) in a single line before and after the block. See: http://commonmark.org/help/
