Python uses Python docx to modify the formatting of Word documents, such as font, color, alignment, indentation, etc

In order to use the Python docx library to modify the format of Word documents, we need to first build a Python development environment and install relevant class libraries. 1. Environmental construction: -Install Python: From the official Python website（ https://www.python.org/ ）Download and install the latest version of Python. -Install pip: pip is a package management tool for Python, used to install third-party class libraries. Execute the following command on the command line to install pip: python -m ensurepip --default-pip -Install the Python docx library: Execute the following command from the command line to install the Python docx library: pip install python-docx 2. Dependent class libraries: -Python docx: This is a Python class library for creating and modifying Word documents. It provides rich functions, including modifying fonts, colors, alignment, and more. The following is a complete implementation example and provides the complete Python code: python from docx import Document from docx.shared import Pt, RGBColor from docx.enum.text import WD_PARAGRAPH_ALIGNMENT #Create a new Word document doc = Document() #Add a paragraph of text paragraph = doc.add_paragraph('Hello, World!') #Modify font size paragraph.runs[0].font.size = Pt(18) #Modify font color paragraph.runs[0].font.color.rgb = RGBColor(0x00, 0x00, 0xFF) #Modify paragraph alignment paragraph.alignment = WD_PARAGRAPH_ALIGNMENT.CENTER #Add another paragraph of text paragraph = doc.add_paragraph('This is a sample paragraph.') #Modify Indent paragraph.alignment = WD_PARAGRAPH_ALIGNMENT.JUSTIFY paragraph.paragraph_format.left_indent = Pt(20) #Save Document doc.save('sample.docx') The above code creates a new Word document and adds two paragraphs of text. The first paragraph uses a font size of 18, blue font color, and centered alignment. The second paragraph uses the default font size, black font color, and is aligned at both ends, with an indentation of 20 points. Finally, save the document as sample.docx. Summary: Through the Python docx library, we can easily modify the formatting of Word documents, including fonts, colors, alignment, indentation, and more. This library provides rich functionality that can meet most needs. At the same time, the library is easy to install and use, making it a good choice for processing Word documents.
