That's weird. It might have to do with the main loop.
I am not familiar with pyscripter, but it might supply
a wx mainloop. However, if that is the case, I would

run without it...
So can you use wx interactively from pyscripter?

I like the transparancy and clearity of python, and the explicit self
fits beautifully. Allowing a second way of defining your methods
would only confuse newbies more I would think.

You're right (I think), but I fail to see the point you're trying

I use python for scientific research too, and for me speed can be

Hi Eric,
First of all, I like your initiative.
I'm not sure if I undestand you correctly, but can't you just
increase indentation after each line that ends with a colon?
That's how I do it in my editor. The user would then only need
to specify when to decrease indentation.

Hi,
If you search the newsgroup you'll find loads of similar posts.
There is not really an agreement on which GUI library is "the one".

QT.

This is reversed in Matlab too, because Matlab is a matrix package and

Better post complete code. I don't see where self.note_name is

you write:

do in explicitly:
use "return str(self) == note"
