一简单的代码：

urls.py:

from django.urls import path
from . import views

urlpatterns = [
path(’’, views.index),
]

views.py:

from django.shortcuts import render

def index(request):
context = {
“username”:‘中国’
}
return render(request,'index.html)

index.html:

二加入类的代码：

views.py

from django.shortcuts import render

class Person():
def init(self,username):
self.username = username

def index(request):
p = Person(“张三”)
context = {
“person”: p
}
return render(request,‘index.html’,context=context)

index.html

三加上字典：

views.py:

from django.shortcuts import render
def index(request):

context = {
    "username": {
        "username":"张三"
    }
}
return render(request,'index.html',context=context)

index.html:

四加上列表与元组：

views.py:

from django.shortcuts import render

def index(request):

context = {
    "username": [
        "张三",
        "李四",
        "王五"
    ]
}
return render(request,'index.html',context=context)

index.html:
