PyPDF2 script problem

[mepyyeti]

Just a script that extracts full PAGES from a pdf and creates a new pdf file from the extraction.

It uses PyPDF2.

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

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? ')

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)):
        new_page = reading.getPage(num)
        pdfWriter.addPage(new_page)
