PyPDF2 script problem

[mepyyeti]

Except I'm trying to extract whole pages from pdf into 1 separate pdf file. I love the use of re in your referenced code...very handy indeed. Unfortunately, it is also a bit above my pay grade (but will study it more definitely).

EDIT: FIXED. it appears while True: on line 36 was the problem.

I've attached the new code. My new question regarding int(foo) is in the comments:

import PyPDF2, os
from functools import partial

def my_user_input(question, type, errmsg):
	while True:
		asked = input(question)
		if asked !='':
				try:
					asked == type(asked)
				except ValueError:
					print(f'"{asked}" is invalid.')
					continue
				else:
					print('ok')
					return asked
		else:
			continue

os.chdir('/home/me/Downloads/')
print(os.getcwd())

str_question = partial(my_user_input,type=str,errmsg='err...something went wrong.')
int_question = partial(my_user_input, type=int, errmsg='err...something went wrong\nDon\t forget u must user NUMBERS...')

pdf_file_name = str_question('please enter filename')
pdf_file_opened = open(pdf_file_name, 'rb')
reading = PyPDF2.PdfFileReader(pdf_file_opened)


pdfWriter = PyPDF2.PdfFileWriter()

#these 2 variables should be integers (A)
beginning = int_question('start at what page number? ')
finish = int_question('end at what page number? ') 

#if I omit int() below I get error suggesting variables are not integers
#my int_question variable clearly REQUIRES input be integers, why must I specify int(finish)???
if int(finish) > int(reading.numPages):
	print(f'there aren\'t {finish} pages in {pdf_file_name}.')
	finish = int_question('end at what page number? ') 
else:
	for num in range(int(beginning)-1, int(finish)): #again, use of int() I don't understand???
		new_page = reading.getPage(num)
		pdfWriter.addPage(new_page)

new_file_name = str_question('please enter new filename WITH .pdf ext...')
new_pdf_file = open(new_file_name, 'wb')
pdfWriter.write(new_pdf_file)
new_pdf_file.close()

Also can anyone quickly run through while True for me? please. thx.
