Our authors tell us that feedback from you is a big motivator. Please take a few moments to let them know what you think of their work.

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").

## All comments excluding tick-boxed quick-comments

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!

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
