Django allows you to retrieve parameters from a URL using request object within a view function. You can access parameters passed in the URL using the request.GET attribute for query parameters or the request.POST attribute for data submitted through a form.

path('article/<int:year>/<int:month>/<slug:slug>/', views.article_detail, name='article_detail'),

You can retrieve the parameters year, month, and slug in the article_detail view function as follows:

def article_detail(request, year, month, slug):
    # Accessing parameters from the URL
    year_param = year
    month_param = month
    slug_param = slug

    # Further processing with the parameters

    # Return the appropriate HTTP response
