Python PPT：无法创建带有粗体标题和常规文本的常规段落

如何解决Python PPT：无法创建带有粗体标题和常规文本的常规段落

嗨，我正在尝试在 ppt 幻灯片上写一个非常简单的段落。

shapes3 = slide4.shapes
shapes3.title.text = 'Hypothesis:Overinvested Categories?'

textBox = shapes3.add_textBox(Inches(3),Inches(1.5),Inches(3),Inches(1))

bullet_point_lvl1 = shapes3.placeholders[1]
bullet_point_lvl1.text= dfh.iat[9,0]+":"+ dfh.iat[9,2] +" text text text text text text text 
text text text text text text text text text text text text text text text" 

bullet_point_lvl2 = bullet_point_lvl1.text_frame.add_paragraph()
bullet_point_lvl2.text = "text text text text text text text text text text text text text 
text text text text text text text text text "
bullet_point_lvl2 = 2

期望的输出
