How to Get List of Fonts Used in a PowerPoint Presentation?

[bowespublishing]

I’m trying to make a list of fonts used in a presentation however I seem to miss a lot of fonts. Any idea what I’m missing please?

fontsinpres = []

self.presentation = slides.Presentation("input.pptx")

                for sld in self.presentation.slides:
                    for shp in sld.shapes:
                        if type(shp) is slides.GroupShape:
                            for j in range(len(shp.shapes)):
                                try:
                                    fontname = shp.shapes[j].text_frame.paragraphs[0].portions[0].portion_format.latin_font
                                    if fontname != None or '':
                                        if fontname not in fontsinpres:
                                            fontsinpres.append(fontname)
                                except:
                                    pass

                        elif type(shp) is slides.Table:
                            tbl = shp
                            for row in range(len(tbl.rows)):
                                for cell in range(len(tbl.rows[row])):
                                    try:
                                        fontname = cell.text_frame.paragraphs[0].portions[0].portion_format.latin_font
                                        if fontname != None or '':
                                            if fontname not in fontsinpres:
                                                fontsinpres.append(fontname)
                                    except:
                                        pass
                            

                        else:
                            try:
                                fontname = sld.shp.text_frame.paragraphs[0].portions[0].portion_format.latin_font
                                if fontname != None or '':
                                    if fontname not in fontsinpres:
                                        fontsinpres.append(fontname)
                            except:
                                pass

@bowespublishing,
Thank you for posting your question.

To get all fonts used in a presentation, you can use fonts_manager. The following code example shows you how to do this:

with slides.Presentation("input.pptx") as presentation:
    fonts = presentation.fonts_manager.get_fonts
