Giudo has suggested adding optional static typing to Python.
(I hope suggested is the correct word.)

An example of the syntax he proposes is:

This means that f() has a 'this' parameter, of type 'tha

I have written a program that interacts with a
command line program.
Roughly speaking, it mimics human interaction.
(With more speed and accuracy, less intelligence.)
It works fine under Linux, using select().
But Windows does not support select for files.
Only for sockets.

No, Windows does provide non-blocking I/O for regular files, but it's a

Hi
I'm looking for a simple Python + Tk text editor.
I want it as a building block/starting point.
I need basic functions only:
open a file, save a file, new file etc.
It has to be open source.
Anyone know of a candidate?

Thanks for this suggestion.
For some reason, I did not think of IDLE as an editor.

I'm sort of wishing to convert TeX tokens into characters.
We can assume the standard (i.e. plain) category codes.
And that the characters are to be written to a file.
This proceess to take place outside of TeX.

Think of a pretty-printer.

Hello
As part of the MathTran project I found myself
wanting to maintain a bijection between long
names and short names.

In other words, I wanted to have two dictionaries
f and g such that
f[a] == b
g[b] == a
are equivalent statements.
