possibly a dumb question !
In using A Mueller's word_cloud package (github link) he says you can change font by using font_path, and this should point a file containing truetype font. e.g. arial.ttf.
In using this on PythonAnywhere - are there .ttf files provided somewhere and if so where ? Or do I need to find the .ttf file myself and if so where would I find it (it just so happened that Arial is the one I am looking for, but also interested in the general case.
