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, x, ...x[n].
Also you have created lists within your list, to no apparent purpose;
x = [float(line.split(',')) for line in open("file.csv")]
