in series: Python for Math Teachers

(Showmedo is undergoing major changes. To report any problems viewing the videos please email us and include browser and OS specifics. Cheers - Kyran.)

Let's use IDLE to define a few functions, including the Euclid's Algorithm for the GCD. Atop the GCD we'll build other functions for listing totatives of N (positives relatively prime to N) and the totient of N (the number of said totatives). We're using the default Python shell to introduce new math ideas ("math through programming").

I was scouting around looking for examples for introducing secondary school teachers to programming. Not being familiar with Haskell, your examples on list comprehension and filter we great (I'm new to Python but not CS).

I'll add your site to the links I provide them.

Thanks - Giovanni

informative and interesting

the videos are pacy but fine otherwise

not a teacher (more interested in developing analyst skills) and still useful for a first introduction of python calculation and function declarative syntax. nice and easy...

easy to understand~

not bad

very good video tutorial, this is my first viewing of kirby's first video tutorial

The video is probably good for someone who has already taken the first few steps to learning/using Python. For those who have not yet got to that level, perhaps not.

The video as really very good overall. I think using the a, b = b, a %b is a little confusing, since it isn't something you'd ever actually want to show students given that its, again, slightly confusing and isn't lexically similar to mathematical notation either.

Nice work. I'm a Ruby programmer by preference (and a maths teacher by trade) but I like the ideas in here. Damn list comprehensions are cool, too!

Moves very quickly through the algorithms - I guess you're assuming familiarity.

awesome. sucinct! practical

Using simple number theory examples really helps to showcase the compact expressive syntax of python!

4. anonymous Mon, 22 Jun 2009 04:13

This is a very good reference material for my students.

Mind boggling!! I came to know about many new things in python on seeing this. Some new stuff in math too, Very interesting to learn things this way rather than reading a book in math. This is REALLY COOL. I can't think of any suggestions for improvement right now but if I get any new idea I'll surely give feedback next time.

Great inspiring video thx a lot

Great Presentation and explanation

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 Kirby
