Slice

Name - Description Default Type
<input> The string or sequence from which characters/elements have to be extracted. [ Any ]BytesString
<output> The extracted characters/elements. Any
From The position/index of the first character or element that is to be extracted (including). Negative position/indices simply loop over the target string/sequence counting backwards. 0 Int[ Int ]&Int&[ Int ]
To The position/index of the last character or element that is to be extracted (excluding). Negative position/indices simply loop over the target string/sequence counting backwards. None Int[ Int ]&Int&[ Int ]
Step The increment between each position/index. Chooses every nth sample to extract, where n is the increment. Value has to be greater than zero. 1 Int

Extracts characters from a string or elements from a sequence based on the start and end positions/indices and an increment parameter. Operation is non-destructive; the target string/sequence is not modified.
