I am new to dJango. I got the following url address `http://127.0.0.1:8000/polls/%7B%25%20url%20'main'%20%25` but my app didn't find the address when looked up my `urls.py` as below.

```
from django.urls import path

from . import views

urlpatterns = [
    path('main', views.main, name='main'),
    path('pageA',views.pageA,name='pageA')
]

```

I know that it can be resolved by applying the regular expression but I failed to get the right solution.
