From de55ffb402b573eef743b30155b3806d08cf729b Mon Sep 17 00:00:00 2001 From: Deep Sharan Date: Sun, 31 Aug 2025 20:56:00 +0530 Subject: [PATCH 1/4] Fix AttributeError: NumberLine object has no attribute 'default_numbers_to_display' - Add missing default_numbers_to_display() method to NumberLine class - Method returns tick range excluding numbers in numbers_to_exclude list - Resolves issue where get_number_mobjects() would fail with AttributeError -
