def say_pdf():

The open function expects a str, bytes or os.PathLike object. In the code above you are trying to open the result of askopenfile.

Just use:

book = askopenfile(mode="rb") # specify the read binary mode
pfreader = PyPDF2.PdfReader(book)

See https://docs.python.org/3/library/dialog.html#tkinter.filedialog.askopenfile.

  • It could be related on opening mode (by default not binary for askopenfile function). See the updated answer. – Giancarlo Romeo Mar 05 '23 at 15:29
