urls.py file:
"""{{ project_name }} URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:

Examples:
Function views

Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path

"""
from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from sign import views
urlpatterns = [
    path('admin/', admin.site.urls),
    path('index/', views.index),
]

views.py
from django.shortcuts import render

def index(request):

Answer 1

你弄错了path模式。与path混淆， re_path和url。

看看文档 Django urls - Path。

urlpatterns = [
    path('admin/', admin.site.urls),
    path('index/', views.index),
]
