How to get the current page no of pdf

Dear Rohsha, thank you for your valued contribute.
Note that the forum is about the RadaeePDF SDK and its capabilities.
RadaeePDF SDK mixes features available in PyPDF2 and PyMuPDF both to edit, inspect and render PDF files within a SDK whose EULA allows the developers to distribute his own code in a closed sources application (I'm aware that also PyPDF2 does, not the same for PyMuPDF without a commercial license).
