If you need an ordered dictionary,

Thanks for your reply Alan,
I am partially asking out of interest, but I also have a potential application.
I'm working on a simulation of cellular growth patterns (basically cell
instances interacting stochastically on a lattice). Anyway, there are many
different cell "behaviors" that I have

I'm sorry, im writing this from my cellphone and there's not a pc around XD.
I didn,t know about the csv module either and had to do over complicated things
to deal with embedded commas, thx for that too :).

readline is the function/method name
readline() executes that function/method and returns a value
try typing in 'type(f.readline)' vs 'type(f.readline())'
you can't .split() a function but you may split its return value
Monika,
Thanks for your help. I got it to work using the following (also had
to spell "delimiter"):
>>> import csv
>>> myfile = open(r'c:\test.txt', 'r')
>>> data = csv.reader(myfile, delimiter=',')
>>> print data
<_csv.reader object at 0x00D41870>
>>> for item in data:
print item
oops it is reader not Reader (all lower case), so this line : data =
csv.Reader(myfile, delimeter = ',')
should be data = csv.reader(myfile, delimeter = ',')

In this case, the standard library provides csv for parsing comma

This is a great suggestion. I too learned how to do threading in
