Definition and Usage
The slice() function returns a slice object.
A slice object is used to specify how to slice a sequence. You can specify where to start the slicing, and where to end. You can also specify the step, which allows you to e.g. slice only every other item.

slice(start, end, step)

| start | Optional. An integer number specifying at which position to start the slicing. Default is 0 |
| end | An integer number specifying at which position to end the slicing |
