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.
