首先安装pycheam，python，djingo。
在pychram中新建一个djingo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
