For Django 2

from django.urls.resolvers import get_resolver, URLPattern, URLResolver

urls = get_resolver()

def if_none(value):
    if value:
        return value
    return ''

def print_urls(urls, parent_pattern=None):
    for url in urls.url_patterns:
        if isinstance(url, URLResolver):
            print_urls(url, if_none(parent_pattern) + if_none(str(url.pattern)))
        elif isinstance(url, URLPattern):
            print(f"{url} ({url.lookup_str})")
            print('----')
print_urls(urls)
