I have grown to like VPython as the curve attribute really seems to do the
trick. If you get it working on a Tkinter canvas, I would like to see the
code as I haven't quite found a way to plot points on to one of those. A
simple graph function in VPython... (it isn't the whole thing, believe

The subject line says it all... Okay I'll add some.
I'm am bored and people are not asking enough questions/answering them to
keep my mind busy. Is there any other mailing list that I can subscribe to
like this one that lets anyone ask and answer questions?
Thanks in advance,

I wondered when someone would ask something like this.

me that something was wrong with the actual shortcut. So I went to the

You can you the exec statement to execute Python code from a string. The string could be from user
input. So for example a user could input 'x*x' and you could do
>>> inp = 'x*x'
>>> func='def f(x): return ' + inp
>>> func
'def f(x): return x*x'
>>> exec func
>>> f(3)

Now you have f(x) def

I am trying to make a program that will plot functions. For that, I need
to be able to get an input (the function to be plotted) and execute it.
So, my question is, how do I use the input? I have found no way to
convert the string to some kind of executable code.
