About Path Converters

Since Django 2.0, url() for URL configurations is replaced with path():

path(
    "blog/<slug:post_slug>/",
    views.post_details,
    name="post_details",
),

These are the default types of URL components called path converters:

Path Converter	Description
str	any string excluding "/"
int	zero or a positive number
slug	ASCII letters or numbers, hyphen, and underscore
uuid	formatted UUID
path	any string including "/"

Custom path converters can be added too. More complex regular expressions can be implemented with re_path().
