Hello.  Back in the '80s, I wrote a fractal generator, which, over the years,
I've modified/etc to run under Windows.  I've been an Assembly Language
programmer for decades.  Recently, I decided to learn a new language,
and decided on Python, and I just love it, and the various IDEs.

Anyway, something I thought would be interesting, would be to export
some data from my fractal program (I call it MXP), and write something
in Python and its various scientific data analysis and plotting modules,
and... well, see what's in there.

An example of the data:
1.850358651774470E-0002
32
22
27
... (this format repeats)

So, I wrote a procedure in MXP which converts "the data" and exports
a csv file.  So far, here's what I've started with:

-----------------------------------------------
import csv

fname = 'E:/Users/jayte/Documents/Python Scripts/XportTestBlock.csv'

f = open(fname)

reader = csv.reader(f)

for flt in reader:
    x = len(flt)
file.close(f)
-----------------------------------------------

This will get me an addressable array, as:

flt[0], flt[1], flt[350], etc...  from which values can be assigned to
other variables, converted...

My question:  Is there a better way?  Do I need to learn more about
how csv file are organized?  Perhaps I know far too little of Python
to be attempting something like this, just yet.

Advice?

Jeff
