Fetch all questions using Python

Question

Currently I am working on the project where I need to collect all questions from the Stack Overflow site.

from stackapi import StackAPI

SITENAME = 'stackoverflow'
SITE = StackAPI(SITENAME)

questions = SITE.fetch('questions')
print(len(questions))

I passed various arguments to the fetch method, but maximum amount of responses that I get is 500.

Is there any way to increase the number of responses using fetch method? If not is there any other way to collect all question from Stack Overflow?
