本文主要介绍如何通过python生成ppt文件，以及借助ppt模板来生成ppt
环境
python 3
python-pptx
安装
pip3 install python-pptx
将文字输出到ppt
效果图
代码
我要评论
from pptx import presentation
# 创建幻灯片 ------
prs = presentation()
title_slide_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(title_slide_layout)
title = slide.shapes.title
subtitle = slide.placeholders[1]
# 设置标题和副标题
title.text = "hello, world!"
subtitle.text = "pip install python-pptx"
prs.save("test.pptx")
图表输出到ppt
效果图
代码
from pptx import presentation
from pptx.chart.data import chartdata
from pptx.enum.chart import xl_chart_type
from pptx.util import inches
# 创建幻灯片 ------
prs = presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])
# 定义图表数据 ---------------------
chart_data = chartdata()
chart_data.categories = ['east', 'west', 'midwest']
chart_data.add_series('series 1', (19.2, 21.4, 16.7))
# 将图表添加到幻灯片 --------------------
x, y, cx, cy = inches(2), inches(2), inches(6), inches(4.5)
slide.shapes.add_chart(
xl_chart_type.column_clustered, x, y, cx, cy, chart_data
)
prs.save('chart-01.pptx')
