使用Python在Python中创建和更新 PowerPoint 演示文稿 – pptx

python-pptx是用于创建/编辑PowerPoint (.pptx) 文件的库。这不适用于 MS Office 2003 和以前的版本。我们可以使用这个库添加形状、段落、文本和幻灯片等等。

安装：在系统上打开命令提示符并编写以下命令：

pip install python-pptx

让我们看看它的一些用法：

示例 1：创建带有标题和副标题幻灯片的新 PowerPoint 文件。

Python3

# import Presentation class
# from pptx library
from pptx import Presentation     
  
# Creating presentation object
root = Presentation()
  
# Creating slide layout
first_slide_layout = root.slide_layouts[0] 
  
""" Ref for slide types: 
0 ->  title and subtitle
1 ->  title and content
2 ->  section header
3 ->  two content
4 ->  Comparison
5 ->  Title only 
6 ->  Blank
7 ->  Content with caption
8 ->  Pic with caption
"""
  
# Creating slide object to add 
# in ppt i.e. Attaching slides 
# with Presentation i.e. ppt
slide = root.slides.add_slide(first_slide_layout)
  
# Adding title and subtitle in 
# slide i.e. first page of slide 
slide.shapes.title.text = " Created By python-pptx"
  
# We have different formats of 
# subtitles in ppts, for simple
# subtitle this method should 
# implemented, you can change
# 0 to 1 for different design
slide.placeholders[1].text = " This is 2nd way"
  
# Saving file
root.save("Output.pptx")
  
print("done")

输出：

示例 2：在 PowerPoint 中添加文本框。

Python3

# import required things
from pptx import Presentation 
from pptx.util import Inches, Pt
  
# Creating Object
ppt = Presentation() 
  
# To create blank slide layout
# We have to use 6 as an argument
# of slide_layouts  
blank_slide_layout = ppt.slide_layouts[6] 
  
# Attaching slide obj to slide
slide = ppt.slides.add_slide(blank_slide_layout)
  
# For adjusting the  Margins in inches 
left = top = width = height = Inches(1) 
  
# creating textBox
txBox = slide.shapes.add_textbox(left, top,
                                 width, height)
  
# creating textFrames
tf = txBox.text_frame
tf.text = "This is text inside a textbox"
  
# adding Paragraphs
p = tf.add_paragraph() 
  
# adding text
p.text = "This is a second paragraph that's bold and italic" 
  
# font 
p.font.bold = True
p.font.italic = True
  
p = tf.add_paragraph()
p.text = "This is a third paragraph that's big " 
p.font.size = Pt(40)
  
# save file
ppt.save('test_2.pptx')
  
print("done")

输出：

示例 3： PowerPoint (.pptx) 文件到文本 (.txt) 文件的转换。

Python3

# import Presentation class
# from pptx library
from pptx import Presentation
  
# creating an object
ppt = Presentation("sample.pptx")
  
# open file in write mode
File_to_write_data = open("File_To_Extract_ppt.txt", "w")
  
# write text from powerpoint
# file into .txt file
for slide in ppt.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: 
                File_to_write_data.write(run.text)
  
# close the file               
File_to_write_data.close()
  
print("Done")

输出：

示例 4：将图像插入 PowerPoint 文件。

Python3

from pptx import Presentation 
from pptx.util import Inches 
  
# Giving Image path 
img_path = 'bg_bg.png' 
  
# Creating an Presentation object
ppt = Presentation() 
  
# Selecting blank slide
blank_slide_layout = ppt.slide_layouts[6] 
  
# Attaching slide to ppt
slide = ppt.slides.add_slide(blank_slide_layout) 
  
# For margins
left = top = Inches(1) 
  
# adding images
pic = slide.shapes.add_picture(img_path,
                               left, top)
  
left = Inches(1) 
height = Inches(1) 
  
pic = slide.shapes.add_picture(img_path, left,
                               top, height = height)
# save file
ppt.save('test_4.pptx')
  
print("Done")

输出：

示例 5：将图表添加到 PowerPoint 文件。

Python3

# import required classes/functions/method
from pptx import Presentation 
from pptx.chart.data import CategoryChartData 
from pptx.enum.chart import XL_CHART_TYPE 
from pptx.util import Inches
  
  
# Create presentation object
ppt = Presentation() 
  
# Adding slide with specific layout
slide = ppt.slides.add_slide(ppt.slide_layouts[6])
  
# Define chart data 
# Creating object of chart
chart_data = CategoryChartData() 
  
# Adding categories to chart
chart_data.categories = ['East', 'West', 'Midwest']  
  
# Adding series
chart_data.add_series('Series 1', 
                      (int(input("Enter Value:")), 
                        int(input("Enter Value:")),
                        int(input("Enter Value:")))) 
  
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 )
  
# Saving file
ppt.save('chart-Tutorial.pptx')
  
print("done")

输出：

示例 6：将表格添加到 PowerPoint 文件中。

Python3

# importing
from pptx import Presentation 
from pptx.util import Inches
  
# create a Presentation object
ppt = Presentation() 
  
# Adding a blank slide in out ppt
slide = ppt.slides.add_slide(ppt.slide_layouts[6])
  
# Adjusting the width !  
x, y, cx, cy = Inches(2), Inches(2), Inches(4), Inches(1.5) 
  
# Adding tables
shape = slide.shapes.add_table(3, 4, x, 
                               y, cx, cy)
  
# Saving the file
ppt.save("Tabel_Tutorial.pptx")
  
print("done")

输出：
