ppt = Presentation('your_presentation.pptx')
slide = ppt.slides[0]  # 假设要处理第一张幻灯片

for shape in slide.shapes:
    if shape.has_chart:
        chart = shape.chart
        if chart.has_category_axis:
            category_axis = chart.category_axis
            # 找到垂直值轴标题
            if category_axis.has_title:
                title = category_axis.title
                # 删除粗体
                title.font.bold = False

ppt.save('modified_presentation.pptx')
