我正在尝试使用 Python 获取幻灯片文件的每张幻灯片的标题。我在 Python 中使用 Presentation 包，但找不到任何指定标题的内容。我有这段代码可以返回powerpoint文件的内容。但我需要指定标题。
from pptx import Presentation
prs = Presentation("pp.pptx")
# text_runs will be populated with a list of strings,
# one for each text run in presentation
text_runs = []
for slide in prs.slides:
for shape in slide.shapes:
if not shape.has_text_frame:
continue
for paragraph in shape.text_frame.paragraphs:
for run in paragraph.runs:
text_runs.append(run.text)
