I recently noticed that Python's built in range( [start,] stop [,step] )
function does not support floating point values for the optional step
parameter ( not 2.6.2 at least ), so until this is fixed, or in cases where you're stuck with it, here's a workaround:
def rangef( min, max, step=1.0 ):
'''rangef( min, max, step=1.0 )\nlike range() but supports floats'''
sf = 1.0 / step # scalefactor
for i in range( int( min * sf ), int( max * sf ) ):
yield i / sf
