List Length

Overview

A small node that simply returns the number of elements in a list as an integer. Insert it when another calculation needs the candidate count—for an index limit, a progress denominator, or a count display.

Usage tips

• To get the last element, send list_length - 1 (math_op(Subtract)) to list_get.index.
• In setups where the list length changes dynamically (such as after a filter), it supplies the current length so dependent calculations remain valid.
• list_map / list_filter expressions already expose count, so this node is unnecessary when the value is only needed inside the expression.

Related nodes

• list_get / list_slice — extraction based on the length
• math_op — calculate from the length
• list_map — situations where the expression's count can replace this node
