An Introduction to Python Objects, using IPython [ID:005]

a series of video-tutorials by Jerol Harrington

These three videos show how objects are used in Python. You can write a lot of code without being especially aware of objects -- until you come to GUI programming: TKInter and especially wxPython. These ShowMeDos will help you make the transition to our wxPython videos.

Video Tutorials

1. An Introduction To Python Objects Using IPython (Part-1)

by Jerol Harrington added 03/07
If you have written any Python code at all, you have been using objects all along. We use the IPython shell to show how objects and methods work at the most basic level. See here (effbot.org) for a brief background to objects.

2. An Introduction To Python Objects Using IPython (Part-2)

by Jerol Harrington added 03/07
In this ShowMeDo we show you how to create your own objects and methods, how to get a handle on self and even venture into ... namespaces

3. An Introduction To Python Objects Using IPython (Part-3)

by Jerol Harrington added 03/07
In this final ShowMeDo, we cover the __init__ method, bound vs unbound methods, passing objects by reference, data attributes, and conclude with some recommendations for further self-development

Showmedo is a peer-produced video-tutorials and screencasts site for free and open-source software (FOSS)- with the exception of some club videos, the large majority are free to watch and download.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Jerol

Thanks, I found you explanation of what an object *is* very helpful, particularly having read the effbot.com link before watching the video. I'm the sort of person who reads "everything is an object" and will stop reading until I've reached a temporary conception of what that means. So I really appreciate your clear reiteration that names (ie labels) are not objects but point to objects and that uniqueness of an object can be checked by using the id() function. You even thought ahead to show that the actual object (e.g. "a literal string") takes the method, not the name; a query I had when I read my first python web intro. Oh, and sneaking iPython in was clever too. Probably better than just making an iPython video.

Hi Patrick,

objx.py is just a script that contains objects such as classes. I use it with the IPython "run" command to load the script in order to demonstrate different qualities of Python's classes. I use IPython all the time with tiny code fragments to test ideas or to clarify points of confusion.

If you are learning the language, I suggest running a Python-aware editor, IPython, and the script in the same directory. Then you can just toggle between IPython and the editor. This is what I do in the tutorial, and what I do for most of my personal programming.

Thank you for your comments.

Noticed the videos were made back in 2006. I just started with Py coming out of Java and was confused but the videos helped 99%. Rating = Excellent. The 1% was the loading of "run objx.py". Is objx.py a class with inner classes in it or just a holder?

Very good and easy to understand, but you need to go a bit faster.

I learned you can call a method from the class rather than an instance, thanks.

I have not looked at IPython for quite a while, I will now have to try it out again.
