I am currently having an issue. I am trying to remove symbology from a shapefile layer. I have a folder of multiple layers, of which each layer has 30 symbols associated to it, but a number of layers only represent 3 or so symbols. However all 30 symbols are displayed in the table of content.
I have been googling like mad today but my search has not produced any results, only finding scripts to change symbology.
I was wondering if it was even possible to do this. My understanding of python would be to find out the attribute value which relates to the symbol and if it equals 0 then it should be removed.

Kind regards
