For this case, there are list comprehensions (or map, but you shouldn't
use it any longer):
>>> a = "0.3434 0.5322 0.3345"
>>> b = a.split()
>>> map(float, b)
[0.34339999999999998, 0.53220000000000001, 0.33450000000000002]
>>> [float(x) for x in b]
[0.34339999999999998, 0.53220000000000001, 0.33450000000000002]
I think it should be easy to apply this to your example above.
