Python Question

Range with step of type float

The documentation basically says that

range
must behave exactly as this implementation (for positive
step
):

def range(start, stop, step):
x = start
while True:
if x >= stop: return
yield x
x += step


It also says that its arguments must be integers. Why is that? Isn't that definition also perfectly valid if step is a float?

In my case, I am esp. needing a
range
function which accepts a float type as its
step
argument. Is there any in Python or do I need to implement my own?




More specific: How would I translate this C code directly to Python in a nice way (i.e. not just doing it via a
while
-loop manually):

for(float x = 0; x < 10; x += 0.5f) { /* ... */ }

Answer

You could use numpy.arange.

EDIT: The docs prefer numpy.linspace. Thanks @Droogans for noticing =)
