Liam,
Here's a nifty re trick for you. The sub() method can take a function as the replacement parameter.
Instead of replacing with a fixed string, the function is called with the match object. Whatever
string the function returns, is substituted for the match. So you can simplify your code a bit

Hi all.
Nothing I can do can fix my problem. It appears as though pythonw.exe is
not working properly in the python 2.4 distribution. I have tried numerous
things to try and fix it. The only way I can run Tk scripts and the like is
to use the pythonw.exe from the 2.3 distribution. This include

You are splitting the list not the item
cols = split(m, '\t')
Better to use a meaningful name too:
for line in cor:
would probably have made the mistake more obvious.

Using sort() with a user compare function is not recommended when you care about performance. The
problem is that the sort function has to call back into Python code for every compare, of which
there are many. The decorate - sort - undecorate idiom is the preferred way to do this in Python <

If you can use Python 2.4 it is very simple using the new key= parameter to sort and
operator.itemgetter:
>>> import operator

One question: This seems to not compute accurately at all when the

With

the code produces

Liam,
I'm sorry to hear you so discouraged.
It sourds like your program has gotten too big for you to clearly understand what it is doing. An
earlier poster suggested that you break your program up into functions. This is a very good idea,
especially if you do it from the start.

Do you want : the roots of 1 ? or something more general ?
Because the nth-roots of 1 are defined by :
r = exp(2*i*pi*k/n) with k = {0,1,...n-1}
If it's more complex ... then I don't know :)

Well, I figured out the memory error relatively easily once I poked
