更改python-pptx中部分文本的字体

Question

I'm using the python-pptx module to create presentations. How can I change the font properties only for a part of the text?

I currently change the font like this:

# first create text for shape
ft = pres.slides[0].shapes[0].text_frame
ft.clear()
p = ft.paragraphs[0]
run = p.add_run()
run.text = "text"

# change font
from pptx.dml.color import RGBColor
from pptx.util import Pt

font = run.font
font.name = 'Lato'
font.size = Pt(32)
font.color.rgb = RGBColor(255, 255, 255)

Thanks!

Answer 1

In PowerPoint, font properties are applied to a run . In a way, it is what defines a run; a "run" of text sharing the same font treatment, including typeface, size, color, bold/italic, etc.

So to make two bits of text look differently, you need to make them separate runs.

Answer 2

As @scanny says in another post. The post

By "different run", it means you should write the text in first color in a run, then afterwards, write the text in the second color in another run as shown below.

There's also an example in the post, I'll just copy and paste it to here

from docx.shared import RGBColor
# ---reuse existing default single paragraph in cell---

paragraph = cell.paragraphs[0]

###(First run)
#---add distinct runs of text one after the other to
# --- form paragraph contents.
paragraph.add_run("A sentence with a ")

###(Second run)
# ---colorize the run with "red" in it. 
red_run = paragraph.add_run("red")
red_run.font.color.rgb = RGBColor(255, 0, 0)


###(Third run)
paragraph.add_run(" word.")
