安装

pip install python-pptx

创建演示文稿

from pptx import Presentation

# 创建演示文稿
prs = Presentation()

# 添加标题幻灯片
slide_layout = prs.slide_layouts[0]  # 标题幻灯片布局
slide = prs.slides.add_slide(slide_layout)

title = slide.shapes.title
subtitle = slide.placeholders[1]

title.text = "演示文稿标题"
subtitle.text = "副标题"

# 保存
prs.save('presentation.pptx')
print("演示文稿已保存")

添加内容幻灯片

from pptx import Presentation

prs = Presentation()

# 添加内容幻灯片
slide_layout = prs.slide_layouts[1]  # 标题和内容布局
slide = prs.slides.add_slide(slide_layout)

# 设置标题
title = slide.shapes.title
title.text = "内容标题"

# 添加文本内容
content = slide.placeholders[1]
text_frame = content.text_frame
text_frame.text = "第一段文本"

# 添加更多段落
p = text_frame.add_paragraph()
p.text = "第二段文本"
p.level = 1

p = text_frame.add_paragraph()
p.text = "第三段文本"
p.level = 2

prs.save('content_slide.pptx')

添加图片

from pptx import Presentation
from pptx.util import Inches

prs = Presentation()

# 添加空白幻灯片
blank_slide_layout = prs.slide_layouts[6]
slide = prs.slides.add_slide(blank_slide_layout)

# 添加图片
left = top = Inches(1)
height = Inches(5)
pic = slide.shapes.add_picture('image.png', left, top, height=height)

# 调整图片大小
pic = slide.shapes.add_picture('image2.png', Inches(5), Inches(1), width=Inches(3))

prs.save('image_slide.pptx')

添加表格

from pptx import Presentation
from pptx.util import Inches

prs = Presentation()

# 添加空白幻灯片
slide_layout = prs.slide_layouts[6]
slide = prs.slides.add_slide(slide_layout)

# 添加表格
rows, cols = 4, 3
left = top = Inches(1)
width = Inches(8)
height = Inches(3)

table = slide.shapes.add_table(rows, cols, left, top, width, height).table

# 设置表头
table.cell(0, 0).text = '姓名'
table.cell(0, 1).text = '年龄'
table.cell(0, 2).text = '城市'

# 填充数据
data = [
    ['张三', 25, '北京'],
    ['李四', 30, '上海'],
    ['王五', 28, '广州']
]

for i, row_data in enumerate(data, 1):
    for j, value in enumerate(row_data):
        table.cell(i, j).text = str(value)

prs.save('table_slide.pptx')

添加形状

from pptx import Presentation
from pptx.util import Inches
from pptx.enum.shapes import MSO_SHAPE

prs = Presentation()

# 添加空白幻灯片
slide_layout = prs.slide_layouts[6]
slide = prs.slides.add_slide(slide_layout)

# 添加矩形
left = Inches(1)
top = Inches(1)
width = Inches(2)
height = Inches(1)
shape = slide.shapes.add_shape(MSO_SHAPE.RECTANGLE, left, top, width, height)
shape.fill.solid()
shape.fill.fore_color.rgb = (0, 0, 255)  # 蓝色

# 添加圆形
left = Inches(4)
shape = slide.shapes.add_shape(MSO_SHAPE.OVAL, left, top, width, height)
shape.fill.solid()
shape.fill.fore_color.rgb = (255, 0, 0)  # 红色

# 添加文本框
left = Inches(1)
top = Inches(3)
width = Inches(6)
height = Inches(1)
textbox = slide.shapes.add_textbox(left, top, width, height)
text_frame = textbox.text_frame
text_frame.text = "这是一个文本框"

prs.save('shapes_slide.pptx')

设置幻灯片背景

from pptx import Presentation
from pptx.util import Inches

prs = Presentation()

# 添加幻灯片
slide_layout = prs.slide_layouts[6]
slide = prs.slides.add_slide(slide_layout)

# 设置背景颜色
background = slide.background
fill = background.fill
fill.solid()
fill.fore_color.rgb = (200, 200, 255)  # 浅蓝色

# 添加标题
left = top = Inches(1)
width = height = Inches(1)
title_box = slide.shapes.add_textbox(left, top, width, height)
title_frame = title_box.text_frame
title_frame.text = "带背景的幻灯片"

prs.save('background_slide.pptx')

修改现有演示文稿

from pptx import Presentation

# 打开现有演示文稿
prs = Presentation('presentation.pptx')

# 遍历所有幻灯片
for slide in prs.slides:
    # 遍历幻灯片中的所有形状
    for shape in slide.shapes:
        if hasattr(shape, "text"):
            print(f"文本: {shape.text}")
            # 修改文本
            if "旧文本" in shape.text:
                shape.text = shape.text.replace("旧文本", "新文本")

# 保存修改后的演示文稿
prs.save('modified_presentation.pptx')

批量生成幻灯片

from pptx import Presentation
from pptx.util import Inches

# 创建演示文稿
prs = Presentation()

# 数据
data = [
    {'title': '产品A', 'content': '产品A的介绍'},
    {'title': '产品B', 'content': '产品B的介绍'},
    {'title': '产品C', 'content': '产品C的介绍'}
]

# 批量创建幻灯片
for item in data:
    slide_layout = prs.slide_layouts[1]
    slide = prs.slides.add_slide(slide_layout)
    
    # 设置标题
    title = slide.shapes.title
    title.text = item['title']
    
    # 设置内容
    content = slide.placeholders[1]
    content.text = item['content']

prs.save('batch_slides.pptx')
print("批量幻灯片已生成")
