In PyPDF2 pdfreader.getNumPages() gives me the total number of pages of a pdf file.

How can I get this using pdfminer?

I hate to just leave a code snippet. For context here is a link to the current pdfminer.six repo where you might be able to learn a little more about the resolve1 method.

As you're working with pdfminer you might print and come across some PDFObjRef objects. Essentially you can use resolve1 to expand those objects (they're usually a dictionary).

from pdfminer.pdfparser import PDFParser
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfpage import PDFPage
from pdfminer.pdfinterp import resolve1

file = open('some_file.pdf', 'rb')
parser = PDFParser(file)
document = PDFDocument(parser)

# This will give you the count of pages
print(resolve1(document.catalog['Pages'])['Count'])
