How to use a decimal range() step value?

Question

Is there a way to step between 0 and 1 by 0.1?

I thought I could do it like the following, but it failed:

for i in range(0, 1, 0.1):
    print i
         


        

Answer 1

Here's a solution using itertools:

import itertools

def seq(start, end, step):
    if step == 0:
        raise ValueError("step must not be 0")
    sample_count = int(abs(end - start) / step)
    return itertools.islice(itertools.count(start, step), sample_count)

Usage Example:

for i in seq(0, 1, 0.1):
    print(i)
