Modify watermarks in Word documents with Python

GroupDocs.Watermark for Python via .NET helps Python developers easily update watermarks in various Word files. Here’s how you can use it in your project:

First, open your Word file by passing it to the Watermarker constructor. You can use a file path, byte stream, or file stream.
Then, find the watermarks you want to change using SearchCriteria, which lets you search for watermark text or properties.
Once found, you can change details like text, font, size, position, color, and more. This gives you full control over how the watermark looks.
After making changes, save the document. You can write the result to a stream or a file path.
