How can I change the character spacing in pptx-python?

Question

What I try to do is change the spacing for each run in the function:

def add_direction_arrows(self):
    global junc_file, junc_file_name
    match_colors_to_type = {"White": RGBColor(255, 255, 255), "Yellow": RGBColor(238, 233, 23)}
    arrows_placeholders = {"NORTH_ARROWS": self.NO.LAN.Organize_arrows_order(),
                           "SOUTH_ARROWS": self.SO.LAN.Organize_arrows_order(),
                           "EAST_ARROWS": self.EA.LAN.Organize_arrows_order(),
                           "WEST_ARROWS": self.WE.LAN.Organize_arrows_order()}
    for slide in junc_file.slides:
        for shape in slide.shapes:
            if shape.name in arrows_placeholders.keys():
                text_frame = shape.text_frame
                text_frame.clear()
                arrows_list = arrows_placeholders[shape.name]
                for arrow in arrows_list:
                    text_frame = shape.text_frame
                    p = text_frame.paragraphs[0]
                    run = p.add_run()
                    run.text = arrow[0] * arrow[1]
                    font = run.font
                    font.bold = False
                  ➜ font.spacing = -10
                    font.size = Pt(49.9)
                    font.color.rgb = match_colors_to_type[arrow[2]]
    junc_file.save(junc_file_name)

I'm not sure if the python-pptx library includes this option, but if it doesn't, what other options do I have? is it possible to add it myself? maybe a way to manually 'press a button' in powerpoint? thanks!

According to the docs python-pptx does not support spacing.

You could take a deep dive into how the library is working internally, and probably add support yourself, but I doubt this is really an option for you.

You can of course edit the powerpoint files by hand later to change this (or even using VBA).
