Learn how to build a console-based Python mail program by merging read mail and send mail, with interactive inputs, subject support, and a simple menu loop.

Learn to use the urllib library in Python to retrieve and inspect web pages, print and save contents to a local file, and access header information for parsing later.

Learn html parsing by converting a webpage to plain text, stripping tags, and displaying content using htmllib, urllib to fetch the page, and a formatter for output.

Parse html to extract links from a webpage using Python, urllib, htmllib, and a formatter, by building getlinks.py and printing each item from the anchor list.

Learn to fetch HTML content with Python and build a screen scraper that extracts and prints stock quotes from Google Finance pages using a span id ref anchored regular expression.

Demonstrate a simple web crawler that visits links from a starting website, parses html, and collects http links using Python and standard libraries.

Create a simple web server with Python's SimpleHTTPServer, running from the command line. Learn to serve local pages like index.html and testpage.html on localhost port 8000.

Learn to start CGI programming with Python by creating a CGI-bin directory and a hello CGI script that outputs HTML to standard output via a CGI HTTP server.

Learn how to process query strings in python using the cgi library's FieldStorage to extract key-value pairs, iterate with a for loop, and output an html response showing the data.

Connect to a SQLite database with Python and CGI, retrieve rows from the films table, and display data as HTML on a web page using an output content type header.

Display database data on a web page by generating HTML with a Python CGI script, fetching SQLite rows, and rendering title, year, and director in a looping output.

Combine CGI programming with database skills to build a film input form that inserts title, year, and director into a database and displays the updated films table.

Learn to update database records with Python via a web form, using an SQL update statement, handling form data with CGI field storage, and verifying changes in the browser.

Learn to parse an XML file with the SAX library by implementing a FilmParser that handles startElement, endElement, and characters to extract films from a films.xml file.

Learn to use the SAX API in Python to search an XML file for a specific element with a findElement.py program, handling start and end element events and characters.

Download and install Django 1.6 by extracting the tar.gz, set the python27 path, run python setup.py install, and verify the Django directory under python27 site-packages to confirm completion.

Set up a Django project using django-admin.py startproject and manage.py. Start the local server with runserver, verify the page at 127.0.0.1:8000, then update settings.py to sqlite3 and run syncdb.

Explore the Django API by entering data into the films model, saving objects with the Python shell, and using __str__ to display fields, with sql-like querying.

Learn to use Django's administration interface by creating a superuser, registering models in admin.py, and managing data—add, delete, and view films via the admin site.

learn to create Django views that display and retrieve information, connect them to the films model, and route via urls.py to render a list of movies.
