Use a generator:

 >>> def iterfloat(start, stop, inc):
...     f = start
...     while f <= stop:
...             yield f
...             f += inc
...
 >>> for x in iterfloat(0.25, 2.25, 0.25):
...     print '%9.2f' % x
...
    0.25
    0.50
    0.75
    1.00
    1.25
    1.50
    1.75
    2.00
    2.25
 >>>
