Hello, World! Leave feedback

A “Hello, World!” example is often the first step when exploring GroupDocs.Redaction for Python via .NET. It serves as a simple test to confirm that your development environment is correctly set up and that the library is functioning as expected.

GroupDocs.Redaction for Python via .NET lets you search, redact, and remove sensitive information from various document formats. A wide range of supported formats makes it versatile for different use cases.

The following steps demonstrate how to redact sensitive information from a document using GroupDocs.Redaction for Python via .NET:

1. Import the groupdocs.redaction classes you need.
2. Describe the redaction (here, an exact phrase to replace with a colored box).
3. Instantiate a Redactor with the path to the sample document.
4. Apply the redaction.
5. Save the result.

The example below replaces every occurrence of the phrase “John Doe” with a semi-transparent red box and saves the redacted document:

from groupdocs.redaction import Redactor
from groupdocs.redaction.options import SaveOptions
from groupdocs.redaction.redactions import ExactPhraseRedaction, ReplacementOptions
from groupdocs.pydrawing import Color

def hello_world():
    # Draw a semi-transparent red box over every occurrence of "John Doe"
    options = ReplacementOptions(Color.from_argb(128, 255, 0, 0))
    redaction = ExactPhraseRedaction("John Doe", options)

    # Load the document, apply the redaction, and save the result
    with Redactor("./sample.docx") as redactor:
        redactor.apply(redaction)
        save_options = SaveOptions()
        save_options.add_suffix = True
        save_options.rasterize_to_pdf = True
        save_options.redacted_file_suffix = "redacted"
        result_path = redactor.save(save_options)

    print(f"Document redacted successfully. Output saved to {result_path}.")

if __name__ == "__main__":
    hello_world()

Binary file (PDF, 1.0 MB)

This example rasterizes the result to a PDF named sample_redacted.pdf, so the redacted content cannot be recovered (save() rasterizes to PDF by default; the redacted_file_suffix option just controls the output name). To keep the original format instead, set rasterize_to_pdf = False.
