Python range function

Python2.x:

for idx in range(0, int(100 / 0.5)):

    print 0.5 * idx      

outputs:

0.0

0.5

1.0

1.5

..

99.0

99.5

Numpy:

numpy.arange would also do the trick.

numpy.arange(0, 100, 0.5)

If you have numpy, here are two ways to do it:

numpy.arange(0, 100, 0.5)

numpy.linspace(0, 100, 200, endpoint=False)
