Range with step of type float

Question

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 1

You could use numpy.arange.

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