How do I iterate through floating point numbers in python?

Question

for i in range(1,10,0.001):
    print(i)

TypeError: 'float' object cannot be interpreted as an integer

`range` can't be a float. `numpy.arange` allows it, but use with caution. — hpaulj, Dec 15 '19 at 01:28

One option:

for i in range(1000,10000):
    print(i/1000)

you shoud use `i / 1000` or `i * 0.001` – furas Dec 15 '19 at 00:37
@furas `i * 0.001` is bad. For example `1001 / 1000` is `1.001` while `1001 * 0.001` is `1.0010000000000001`. – Stefan Pochmann Dec 15 '19 at 00:45

Or `for i in (j*0.001 for j in range(1000, 10000):` – rici Dec 15 '19 at 00:46
Thanks, fixed using numpy for i in np.arange(0,10,0.1): – Python Dec 15 '19 at 01:34
