bpy.context.object.active_material_index = 1
bpy.ops.object.material_slot_remove()
bpy.context.object.active_material_index = 2
bpy.ops.object.material_slot_remove()

You can set the index of the list to 0, iterate through all slots and override the context of material_slot_remove():

for obj in bpy.context.selected_editable_objects:
 obj.active_material_index = 0
 for i in range(len(obj.material_slots)):
 bpy.ops.object.material_slot_remove('object': obj)
