urlpatterns = [
    path('admin/', admin.site.urls),
    path('articles/2020/', views.special_case_2020),
    # 无名分组,按位置传参
    re_path('^articles/([0-9]{4})/$', views.articles_year),
    # 有名分组， 按关键字传参
    re_path("^articles/(?P<year>[0-9]{4})/$", views.articles_year),
    #无名分组，年月
    # re_path("^articles/([0-9]{4})/([0-9]{2})/$", views.articles_y_m),
    # 有名分组， 年月
    re_path("^articles/(?P<y>[0-9]{4})/(?P<m>[0-9]{2})/$", views.articles_y_m),
]
