if new_leader != partition.replicas[0]:

partition.replicas[0] throws IndexError. Should be checked for null or empty before the index is referred

partition.replicas should theoretically not be null. It can be empty, but in that case your partition has zero replicas, and it doesn't make any sense to reorder it.
