Django是Python中Web开发的最有代表性的框架之一。本文将简单介绍如何入门Django开发。  
　　首先确保你的linux系统已安装django模块。打开Python3,利用以下命令可找到django所在目录：

>>> import django
    >>> print(django.__path__)

笔者显示的是：

['/usr/lib/python3/dist-packages/django']

接下来开始django开发！首先切换到django目录,新建poem项目：

django-admin.py startproject poem

输入tree poem,查看poem项目的树结构：  
![这里写图片描述][format_png]  
在urls.py的urlpatterns列表中添加：

url(r'^$', 'poem.views.output'),

在/poem/poem文件夹下，创建views.py文件，输入代码：

from django.http import HttpResponse
     
    def output(request):
        title = "<h1>When You Are Old</h1>"
        author = "<h2>William Butler Yeats</h2>"
        content = """ When you are old and grey and full of sleep,<br/> And nodding by the fire, take down this book,<br/> And slowly read, and dream of the soft look<br/> Your eyes had once, and of their shadows deep;<br/> How many loved your moments of glad grace,<br/> And loved your beauty with love false or true,<br/> But one man loved the pilgrim soul in you,<br/> And loved the sorrows of your changing face;<br/> And bending down beside the glowing bars,<br/> Murmur, a little sadly, how love fled<br/> And paced upon the mountains overhead<br/> And hid his face amid a crowd of stars.<br/> """
        return HttpResponse([title, author, content])

进入poem文件夹，输入命令：

python3 manage.py runserver 8000

打开浏览器，输入localhost:8000，页面如下图：
