Discover Python, Part 8: Reading and writing data using Python's input and output functionality


Discover Python, Part 8: Reading and writing data using Python's input and output functionality
In this article, you learn how to work with files. First, we review a simple way to output data in Python, using the print statement, then learn about the file object, which is used by Python programs to read and write data to a file. The different modes with which a file can be opened are demonstrated, and the article concludes by showing how to read and write a binary file.

Python Web frameworks, Part 2: Web development with TurboGears and Python


Python Web frameworks, Part 2: Web development with TurboGears and Python
In this second article of a two-part series, we demonstrate TurboGears, another open source MVC-style Web application framework based on Python. Where the first article was an introduction to the Django framework, this one shows how to use TurboGears to create a Web-based shopping application and concludes with a comparison between Turbogears and Django.

Discover Python, Part 7: Explore the Python type hierarchy


Discover Python, Part 7: Explore the Python type hierarchy
This article returns to the exploration of the Python type hierarchy and introduces the Python dictionary container type. Unlike the Python tuple, string, and list container types discussed in previous articles, the dictionary type is an unordered container that relies on a key-to-value mapping. As a result, items in a dictionary are accessed by a key value and not by their location within a sequence. The unique features of the dictionary type may seem unusual, but they provide a great deal of power when used properly.

Discover Python, Part 9: Putting it all together


Discover Python, Part 9: Putting it all together
Previous articles in this Discover Python series have discussed a number of topics that confront beginning Python programmers, including variables, container objects, and compound statements. This article builds on these concepts to construct a complete Python program. It introduces Python functions and modules and shows how to build a Python program, store it in a file, and run it from the command line.

Charming Python: Scaling a new PEAK


Charming Python: Scaling a new PEAK
The Python Enterprise Application Kit (PEAK) is a Python framework for rapidly developing and reusing application components. While Python itself is already a very high-level language, PEAK provides even higher abstractions. One fairly recent capability added to PEAK is the capability to create generic functions and specifically to dispatch them on predicates, not simply on type. Sounds mysterious? Let's investigate.

CherryPy for CGI programmers The CherryPy application framework


CherryPy for CGI programmers
The CherryPy application framework for Python makes Web applications easier to write than plain Common Gateway Interface (CGI). At the same time, it's simple -- not full of little-used features -- and easy to learn. This introduction shows everything needed to write Web applications with CherryPy.

Sockets programming in Python This tutorial shows how


Sockets programming in Python
This tutorial shows how to develop sockets-based networking applications using Python. In this tutorial, you first learn a few Python basics and see why Python makes a good network programming language. Then you move on to the basic sockets features of Python, using a sample chat application as a guide, and look at several other, high-level, classes that provide asynchronous communications.

Discover Python, Part 6: Programming in Python
This article explores the Python for loop. The for loop is used to iterate through the items in a Python collection, including the Python tuple, string, and list container types discussed in previous "Discover Python" articles. The for loop can also be used to access elements from a container type by using the range (or xrange) method. In addition, you can use the range method to execute a group of statements a specific number of times within a for loop.

Discover Python, Part 3: Explore the Python type hierarchy
Unlike many other programming languages, the Python language does not include a special data type to handle a single character, such as "a" or "z." In contrast, Python takes a different approach: It uses a class designed especially for holding sequences of characters. This article introduces the string class and demonstrates different ways in which you can use a string within Python.

Discover Python, Part 5: Programming in Python
This article begins to demonstrate how to do things in Python by focusing on flow control, which is one of the simplest methods for writing programs. In this programming model, data is manipulated -- perhaps from a user interface, sensors, or a file; depending on the value of the data or resulting expressions, different actions are taken. Python provides several flow control mechanisms. This article discusses the if statement, and the while and for loops.
