Currently, delete_edges raises an exception if any provided edge does not exist in the hierarchy. This is inconvenient for bulk or automated operations where edge lists may be partially invalid.

Proposal

Add an optional argument:

skip_invalid_edges: bool = False

Behavior

False (default): keep current strict behavior

True: silently skip non-existing edges and delete only valid ones

Example

hierarchy.delete_edges(
    edges=[("Parent1", "Child1"), ("ParentX", "ChildX")],
    skip_invalid_edges=True
)

Benefit

Improves robustness of bulk operations and aligns with existing skip_... patterns in TM1py.
