Hello, World! Leave feedback

A “Hello, World!” example is often the first step when exploring GroupDocs.Parser 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.Parser for Python via .NET extracts text, tables, images, metadata and more from documents of various formats. A wide range of supported formats makes it versatile for different use cases.

The following steps demonstrate how to extract the text of a document using GroupDocs.Parser for Python via .NET:

1. Import the Parser class from groupdocs.parser.
2. Open a Parser with the path to the sample document.
3. Call get_text() to extract the text.
4. Print the result.

The example below extracts the text of a four-page PDF report and prints it:

from groupdocs.parser import Parser

def hello_world():
    # Open the document and extract its text
    with Parser("./sample.pdf") as parser:
        text = parser.get_text()

        # get_text() returns None for a format without text extraction
        if text is None:
            print("Text extraction isn't supported for this format")
        else:
            print(text)

if __name__ == "__main__":
    hello_world()

get_text() returns the text as a str. To extract one page, pass its index: get_text(0) returns the text of the first page. The first Parser in a process takes 20-30 seconds while the engine loads; documents opened after that take a fraction of a second.
