From last saved cursor?

[jobqueue]

        cursor = tweepy.Cursor(api.followers_ids, screen_name=handle)
        for page in cursor.pages():
                         process(page)

In case if process failed, I'd like to save something about the last succeeded cursor/page position and continue the operation from the cursor position, is that possible with Tweepy?

tweepy_cursor = tweepy.Cursor(self.api.followers_ids, screen_name=handle).pages()
save_obj = {}
while True:
    try:
         page = tweepy_cursor.next()
         cursor = tweepy_cursor.next_cursor
         for follower in page:
               writer.writerow([follower])
     except StopIteration:
         break

     # update and write save file in case we need to resume later
     save_obj['cursor'] = cursor
     self.write_save_file(save_obj=save_obj)

If the pagination is by cursor, as is the case with API.followers_ids, then the iterator you're using is a CursorIterator returned by Cursor.pages:

tweepy/tweepy/cursor.py

Lines 11 to 31 in 8ce6e8c

	class Cursor(object):
	"""Pagination helper class"""
	def __init__(self, method, *args, **kargs):
	if hasattr(method, 'pagination_mode'):
	if method.pagination_mode == 'cursor':
	self.iterator = CursorIterator(method, args, kargs)
	elif method.pagination_mode == 'id':
	self.iterator = IdIterator(method, args, kargs)
	elif method.pagination_mode == 'page':
	self.iterator = PageIterator(method, args, kargs)
	else:
	raise TweepError('Invalid pagination mode.')
	else:
	raise TweepError('This method does not perform pagination')
	def pages(self, limit=0):
	"""Return iterator for pages"""
	if limit > 0:
	self.iterator.limit = limit
	return self.iterator

In which case, you can use the prev_cursor and next_cursor attributes of the CursorIterator:

tweepy/tweepy/cursor.py

Lines 61 to 68 in 8ce6e8c

	class CursorIterator(BaseIterator):
	def __init__(self, method, args, kargs):
	BaseIterator.__init__(self, method, args, kargs)
	start_cursor = kargs.pop('cursor', None)
	self.next_cursor = start_cursor or -1
	self.prev_cursor = start_cursor or 0
	self.num_tweets = 0
