Hi Tom,
Glad you got it working with Danny's help.
I'll throw in some style points too.

You might find it easier to use a for loop.
you could for example use
for s in input:
to replace most of the above code and, in the process,
eliminate the need for N completely, see below...
> s = s[:-2]
> T[N] = s.split(',')
Since you are using append elsewhere why not for T too?
And if you store the split result in a local value before
putting it into T you can use that variable in all the
following appends to save indexing T...
> date.append(T[N][0])
> open.append(float(T[N][1]))
> hi.append(float(T[N][2]))
> lo.append(float(T[N][3]))
> close.append(float(T[N][4]))
> vol.append(float(T[N][5]))
> N+=1
And with the for loop you don;t need to increment N either.

And you can use len(T) to replace N here.
> T[i]
This doesn't do anything! :-)
> print T[i]
> print date[i], open[i], hi[i], lo[i], close[i], vol[i]
> print T[1][2], T[0][0]
> z = (hi[2] +lo[2])/2.0
> print z
