Python PDF to Text Translation with Google Translate API

You can use the PyPDF2 library to read the contents of a PDF file and the google-cloud-translate library to translate the text. Here is an example function that translates a PDF file to a target language using Google Translate API:

import PyPDF2
from google.cloud import translate

def translate_pdf(pdf_path, target_language):
    # Read the contents of the PDF file
    with open(pdf_path, 'rb') as file:
        pdf_reader = PyPDF2.PdfFileReader(file)
        num_pages = pdf_reader.numPages
        pdf_text = ''
        for page_num in range(num_pages):
            page = pdf_reader.getPage(page_num)
            pdf_text += page.extractText()

    # Use Google Translate API for translation
    translate_client = translate.TranslationServiceClient()
    parent = translate_client.location_path('<project_id>', 'global')
    response = translate_client.translate_text(
        parent=parent,
        contents=[pdf_text],
        mime_type='text/plain',
        source_language_code='',
        target_language_code=target_language
    )

    # Output the translation result
    for translation in response.translations:
        print(translation.translated_text)

You need to replace <project_id> with your actual Google Cloud project ID. Also, make sure you have the necessary credentials set up to access the Google Translate API.
