In addition to Jay (it's csv module not cvs) and Michael's responses I add:

It is rarely a good idea to assign a bunch of variables (x1...xn).

What's the reason you're doing this?

You can just create another list holding the floated values. If you 
assign this list to x then you can refer to x[0], x[1], ...x[n].

Also you have created lists within your list, to no apparent purpose;

Consider:

x = [float(line.split(',')[1]) for line in open("file.csv")]
