The % is a python symbol for a single line magic command (search about it). What is actually happening here is using widgets from matplotlib and a certain style found in the directory file given in the second line.

The %matplotlib syntax causes the output from matplotlib to be embedded in the notebook.

If you search for “magic commands”, you’ll get a lot of explanations about the “double_underscore” (dunder) syntax that Python uses internally to define default built-in functions. That has naught to do with the % inline syntax.
