## [numpy.roll](https://numpy.org/doc/stable/reference/generated/numpy.roll.html)
```python
numpy.roll(a, shift, axis=None)
```
> Roll array elements along a given axis.
>
> Elements that roll beyond the last position are re-introduced at the first.
```python
import numpy as np
a = np.arange(0, 6).reshape((2, 3))
print(a)
print()
print(np.roll(a, shift=1))
print()
print(np.roll(a, shift=2))
print()
print(np.roll(a, shift=3))
print()
print(np.roll(a, shift=4))
```
Output:
