如何在python中更改pptx中的文本颜色和文本字体？

Question

我有数百个演示文稿。其中我需要更改每个文本的颜色和字体以及每张幻灯片的背景颜色。这在Python中如何实现呢？ 我尝试了解 pptx 模块，但在 Youtube 上没有找到合适的视频。如何更改现有演示文稿中先前列出的参数？

解决方案：

想法是循环加载每个文件名，处理更改，然后保存新文件。当前设置为保存现有文件，因此您可能需要更改该文件或制作当前文件的备份副本。我对此进行了测试，它按预期工作。

from pptx import Presentation
from pptx.dml.color import RGBColor

file_list = ["file1.pptx", "file2.pptx"]

for file_name in file_list:

    # Open the current file
    ppt = Presentation(file_name)

    # Get all slides in the presentations
    slides = ppt.slides

    # Loop over each slide to process what's inside
    for slide in slides:

        # Access slide background and fill with solid color
        background = slide.background
        fill = background.fill
        fill.solid()
        fill.fore_color.rgb = RGBColor(0, 0, 255)

        
        # Get list of all shapes in slide
        for shape in slide.shapes:

                # If this is a text box then access the text and change the color
                if not shape.has_text_frame:
                    continue
                text_frame = shape.text_frame

                for p in text_frame.paragraphs:
                    for run in p.runs:
                        font = run.font
                        font.color.rgb = RGBColor(255, 0, 0)

    # Save over the existing file
    ppt.save(file_name)
