To download PDFs from search results without using web browsers in Python, you will need to install the 'googlesearch-python' library.
The code provided includes a 'search_pdfs' function that searches for PDFs based on a given query using the 'googlesearch' library.
Once the PDF links are obtained, the 'download_pdf' function is used to download the PDFs and save them to a specified directory.
The example usage demonstrates how to search for PDFs and download them to your computer, prompting for a search term and displaying the downloaded PDF links.
