pygambit.gambit.Game.insert_move#

Game.insert_move(node: Selector, player: str, actions: list[str]) → None#

Insert a move for player prior to the node identified by node, with actions labeled according to actions. The node becomes the first child of the newly-inserted node.

player must be a personal player; use insert_event to insert a chance move.

node is a Selector (an H-built expression, evaluated against this game) that must resolve to exactly one node.

Changed in version 17.0.0: node is now a Selector; a Node or str is no longer accepted directly – build one with H.

Raises:

  • TypeError – If node is not a Selector.

  • UndefinedOperationError – If actions is empty.

  • KeyError – If no player in the game has label player.

  • ValueError – If node does not resolve to exactly one node, or actions contains an empty or a duplicated label.
