Question

Say I want to loop from 0 to 100 but with a step of 1/2. If you try

for i in range(0, 100, 0.5):
    whatever

Error:

the step must not be 0

Question:
Is there any built-in way in Python 2.x to do something like this?

Answer 1

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)
