Pull request overview

Updates the NetworkingGroup.ip_addresses_assign API to send assignments as an array/list (matching the Linode API contract) instead of a dict wrapper, and aligns unit tests accordingly.

Changes:

• Update ip_addresses_assign to iterate over and submit a list of assignment objects.
• Update unit test to pass and assert list-shaped assignments.

Changing ip_addresses_assign to accept a bare list is a breaking change for any callers that were previously passing {"assignments": [...]}. Consider supporting both shapes for backward compatibility (e.g., if assignments is a dict with an assignments key, unwrap it) or at least raise a clearer error when a dict is provided (current loop will iterate dict keys and raise a generic Invalid assignment).

Suggested change

	for a in assignments:
	if not "address" in a or not "linode_id" in a:
	if isinstance(assignments, dict):
	if "assignments" in assignments:
	assignments = assignments["assignments"]
	else:
	raise ValueError(
	"Invalid assignments payload: expected a list of assignments "
	"or a dict containing an 'assignments' key, got {}".format(
	assignments
	)
	)
	if not isinstance(assignments, list):
	raise ValueError(
	"Invalid assignments payload: expected a list of assignments, got {}".format(
	type(assignments).__name__
	)
	)
	for a in assignments:
	if not isinstance(a, dict) or "address" not in a or "linode_id" not in a:
