Python Koans virtualenvwrapper 2.9 — virtualenvwrapper v2.9 documentation virtualenvwrapper is a set of extensions to Ian Bicking’s virtualenv tool. The extensions include wrappers for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies. Features¶ Organizes all of your virtual environments in one place.Wrappers for managing your virtual environments (create, delete, copy).Use a single command to switch between environments.Tab completion for commands that take a virtual environment as argument.User-configurable hooks for all operations (see Per-User Customization).Plugin system for more creating sharable extensions (see Extending Virtualenvwrapper). Introduction¶ The best way to explain the features virtualenvwrapper gives you is to show it in use. First, some initialization steps. Now we can install some software into the environment. We can see the new package with lssitepackages: Support¶ Shell Aliases¶ License¶

Code Like a Pythonista: Idiomatic Python In this interactive tutorial, we'll cover many essential Python idioms and techniques in depth, adding immediately useful tools to your belt.

In the tutorial I presented at PyCon 2006 (called Text & Data Processing), I was surprised at the reaction to some techniques I used that I had thought were common knowledge. Many of you will have seen some of these techniques and idioms before. These are the guiding principles of Python, but are open to interpretation. import this

ronnix/fabtools - GitHub Dev Explorer - Developing Console Interfaces Using Python and ... Date Published: 18/05/2009 14:39 In general I spend quite a lot of time building python applications and scripts for home and office use. These vary from scripts at home for cleaning up my music library to decent sized applications implementing business logic. One thing that can be quite difficult when carrying out these tasks is interacting with the code I am writing without building a fully fledged interface. When programming this way I use the python curses library to allow me to build a quick temporary command line interface to use and test my application/script. When I first started using curses I found it difficult understand how it worked. In this article I am going to document the basics of python curses programming to help readers understand the concept and curses' benefits. Note Just a quick note to say this is a basic introduction to curses designed to familiarise people who have never used the library before. About Curses The Basics import curses screen = curses.initscr() #!

Parser Combinators Made Simple April 18, 2011 # Parsing theory has been around for quite a long time, but it is often thought of as magic by the swarms of people who haven't bothered to read about it, and see how plain and dry it actually is. Algorithms for parsing LR(k) grammars (meaning Left-to-right, Right-most derivation, k tokens lookahead) for instance, normally just traverse a state machine that was computed before hand (either by hand, or by using a parser generator such as bison or yacc). Sure, there are many things to trip on, tedious to track down ambiguities, and other issues, but the general theory of parsing has remained unchanged for years—one might say, it is a solved problem.[1] When learning about parsing for the first time though, the idea of a recursive descent parser is often taught first. Recursive descent parsers, are relatively simple to reason about, to write and to shoot yourself in the foot with. This sounds boring and tedious, and in fact is. Why don't we return None here? Success!
