Hmm. Are the strings and floats in a repeating pattern, or randomly
sprinkled around, or what?
Assigning a bunch of variables like this may not be the best way to
handle the data. Perhaps you could just keep them in a list?
Why are you doing this? How many lines are in the data file?

This could be
data.append(columns[1])
there is no need to make a nested list.

Without the extra nesting it would be
x1 = float(data[0]); etc.
