## [numpy.arange](https://numpy.org/doc/stable/reference/generated/numpy.arange.html)
```python
numpy.arange([start, ]stop, [step, ]dtype=None, *, like=None)
```
> Return evenly spaced values within a given interval.
>
> arange can be called with a varying number of positional arguments:
>
> **arange(stop)** : Values are generated within the half-open interval [0, stop) (in other words, the interval including start but excluding stop).
>
> **arange(start, stop)** : Values are generated within the half-open interval [start, stop).
>
> **arange(start, stop, step)** Values are generated within the half-open interval [start, stop), with spacing between values given by step.
>
> For integer arguments the function is roughly equivalent to the Python built-in range, but returns an ndarray rather than a range instance.
>
> **When using a non-integer step, such as 0.1, it is often better to use numpy.linspace.**
