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：
poem项目的树结构
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：

这样我们就完成了一个简单的django项目的开发。期待下期分享~~
