[Tutor] Need Help on Assignment

I have imported a text file consisting of lines of csv. Each line 
consists of six items separated by commas. I have converted this file 
into a matrix of string variables, T[i]. Now I want to extract each of 
the individual strings, convert five them to floats, and save them in 
individual vectors. That is, I'd like to convert each T[i] into date[i] 
(a string), open[i] (a float) etc. Python doesn't like the ways I've 
attempted to make these assignments.

T[i], which is a six-column matrix, works fine. However, if I say 
date[i] = T[i][0], it doesn't like this. I've tried several variations 
on this but with no success. Things like:  [date[i],open[i], etc] = T[i] 
didn't work either.

What do I need to do to make this type of assignment?

Thank you.
