首先安装Pycharm，Python，Djingo。

在PyChram中新建一个Django项目

在web2目录下新建views.py文件，目录如下：

接下来在views.py文件中编写helloworld代码：
# -*- coding: utf-8 -*
from django.http import HttpResponse
 
def hello(request):
    return HttpResponse("Hello world！ This is my first trial. [笔记]")

还需要配置urls.py文件完成映射
from django.conf.urls import patterns, include, url
from web2.views import hello
from django.contrib import admin
from django.conf.urls import *
admin.autodiscover()
 
urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'web2.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),
 
    url(r'^admin/', include(admin.site.urls)),
    ('^hello/$', hello),
)

一定要先导入hello
from web2.views import hello然后启动项目，在浏览器打开
http://127.0.0.1:8000/hello/
