Code to Display the Number of URLs in Django

During an IT audit, I needed to represent the size of an application, so I decided to use the total number of URLs in Django to signify the application's scale.

from django.urls.resolvers import get_resolver
root_resolver = get_resolver()


def _join_namespace(a, b):
    return (a + ':' if a else '') + (b or '')


def _count_urls(namespace, resolver):
    count = 0
    _namespace = _join_namespace(namespace, resolver.namespace)
    for ns, (prefix, res) in resolver.namespace_dict.items():
        count += _count_urls(_namespace, res)

    for n, l in resolver.reverse_dict.items():
        if callable(n):
            continue
        count += 1
    return count


print('URLS count:', _count_urls('', root_resolver))

This script calculates and prints the total number of URLs in a Django application. By analyzing the URL patterns, it sums up all the available endpoints, thereby providing an indicator of the application's size.
