As Ken is the author of these changes, has an assignment for Emacs and is keen
to see them installed, to move things along I have installed them.

My understanding is that the advantage of Pdbtrack is that you can start to
debug on the fly.  There's a small example attached below using a file called
fibo.py (which I probably pinched from somewhere, but I can't remember where).
However, as I've said before I'm not a Python programmer and Ken can probably
explain better.

Note that python-shell is similar to run-python and one should probably
eventually subsume the other.

So, all credit to Ken, complaints to me... no, what the heck, give Ken your
grief too!

More seriously, this is only on the trunk and I can always revert these changes
if there are problems.

Enjoy!


Ken,

Have you got write access yet?

# Fibonacci numbers module (fibo.py)

    a, b = 0, 1
    while b < n:
        print b,
        a, b = b, a+b

def fib2 (n): # return Fibonacci series up to n
    result = []
    a, b = 0, 1
    while b < n:
        result.append (b)
        a, b = b, a+b
    return result
