first i want to say that it is very simple tocreate an web site using the Django framework.
ubuntu 11.10 python 2.7.2+
i am assume you run the follow commands as root
install pip:
# apt-get install python-pip

install Django using pip:
# pip install Django

create a djangoproject:
# django-admin.py startproject myweb
now there is a myweb directory in your current location. that's seewhat are there in it:
# cd myweb; ls -R
.:
manage.py myweb
./myweb:
__init__.py   settings.py wsgi.py  urls.py

then create my firstapp:
#python manage.py startapp myapp
#ls myapp
_init__.py  models.py views.py   tests.py

edit myapp/views.py
   #vimmyapp/views.py
   1 # Create your viewshere.
   2 import commands
   3 from django.http importHttpResponse
   4 from django.template importloader, Context
   5 from django.shortcuts importrender_to_response
   6
   7
   8 def index(request):
  9        ls = commands.getoutput('ls')
10        file_list = ls.split('\n')
11        return render_to_response('path/index.html',{'file_list':file_list})

make the template htmlfile
# mkdir /my/path/to/python/template/; cd/my/path/to/python/template/
# vim index.html
   1<html>
   2<title>files</title>
   3<body>
   4<h2>you can upload thesefiles</h2>
   5 {% for file in file_list%}
  6        <li>{{file}}</li><br/>
   7 {%endfor%}
   8</body>
   9</html>

edit myweb/setting.py
#vim myweb/setting.py
12 DATABASES = {
13    'default': {
14        'ENGINE': 'django.db.backends.sqlite3', # Add'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
15        'NAME':'/myhome/django/myweb/sql.db',  # Or path to database file if using sqlite3.
16        'USER':'',                     # Not used with sqlite3.
17        'PASSWORD':'',                 # Not used with sqlite3.
18        'HOST':'',                     # Set to empty string for localhost. Not used with sqlite3.
19        'PORT':'',                     # Set to empty string for default. Not used with sqlite3.
20    }
21 }
.............................
108 TEMPLATE_DIRS = (
109        '/my/path/to/python/template',
110    # Put strings here, like "/home/html/django_templates" or"C:/www/django/templates".
111    # Always use forward slashes, even on Windows.
112    # Don't forget to use absolute paths, not relative paths.
113 )
114
115 INSTALLED_APPS = (
116    'django.contrib.auth',
117    'django.contrib.contenttypes',
118    'django.contrib.sessions',
119    'django.contrib.sites',
120    'django.contrib.messages',
121    'django.contrib.staticfiles',
122    # Uncomment the next line to enable the admin:
123    # 'django.contrib.admin',
124    # Uncomment the next line to enable admin documentation:
125    # 'django.contrib.admindocs',
127    'myapp',
126 )

edit myweb/urls.py
# vim myweb/urls.py
   1 from django.conf.urls importpatterns, include, url
   2
   3 urlpatterns =patterns('',
  4        url(r'^$', 'getpath.views.index'),
   5 )

now it is the time to start my web site
# python manage.py runserver

open your browser and type "127.0.0.1:8000" in the url, yes, thereis the web site we just create
