title: Changing font for part of text in python-pptx
body: <p>I'm using the python-pptx module to create presentations. 
  How can I change the font properties only for a part of the text?</p>
  
  <p><strong>I currently change the font like this:</strong></p>
  
  <pre><code># 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)
  </code></pre>
  
  <p>Thanks!</p>
