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 should 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] []
