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

more_itertools is a third-party library that implements a numeric_range tool:

import more_itertools as mit


for x in mit.numeric_range(0, 1, 0.1):
    print("{:.1f}".format(x))

Output

0.0
0.1
0.2
0.3
0.4
0.5
0.6
0.7
0.8
0.9

This tool also works for Decimal and Fraction.
