Hi Shi Mu,
Can you describe how you fixed it? The only diff between the two programs
that I see is that you repositioned the setting of the frame variable.

any python code for middle school geometry teaching use?

Hi all,
What is the syntax if I want to work out what percentage 42 is out of 250?

If there's not code for geometry, let's write some!! What,
precisely, are you looking for? Or, better yet, do you have the
resources to have you students write the code after teaching them "just
enough" python? I did that with a physics class a few years ago
and the students loved it!

If you want it as a factor to multiply / divide by something:
perc = 42/250
If you want it to "read" as percentage:
perc_100 = (42/250)*100

You might be interested in PyGeo. I think it is more oriented toward
visualization than calculation but it is definitely intended to aid in teaching

You could try:
percentage = (42 * 250)/100
This gives the answer 105.

And that sounds weird, doesn't it? 42 is smaller than 250, so I'd expect it
to be less than 100% of the value... In fact, it is

I neglected to mention that the list x_list was created by x_list = [] and
then a series of x_list.append(y), where y are class instances with a
variety of variables, one of which I want to use as a sort key.

Hi RC,

So, a list of instances/classes then.
You'll have to pass a custom function.

integers
if objA < objB:
result = -1

Hi Matt,
The main advantage of IronPython is access to the .NET framework in Python.
For most Python scripts I run, there is no speed advantage due to the
overhead of loading the framework (but then, I have an old computer.)
But, I like being able to poke .NET within a Python environment, as I di
