List Slice

Functionality

Select a slice from a list. The node is data type agnostic, meaning it makes no assumptions about the data you feed it. It shoudld accepts any type of data native to Sverchok.. Functionality is a subset of python list slicing, the stride parameter functionality isn’t implemented.

Inputs

Input	Description
Data	The data - can be anything
Start	Slice start, allows negative python index
Stop	Slice stop, allows negative python index

Parameters

Level

It is essentially how many chained element look-ups you do on a list. If SomeList has a considerable nestedness then you might access the most atomic element of the list doing SomeList[0][0][0][0]. Levels in this case would be 4.

Start

Start point for the slice

Stop

Stop point for the slice.

Outputs

Slice, the selected slices. Other, the list with the slices removed.

Examples

Trying various inputs, adjusting the parameters, and piping the output to a Debug Print (or stethoscope) node will be the fastest way to acquaint yourself with the inner workings of the List Item Node.

Some slice examples. >>> l [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> l[1:-1] [1, 2, 3, 4, 5, 6, 7, 8] >>> l[0:2] [0, 1] >>> l[-1:2] []
