TransportError while deleting elasticsearch index by Python script

Question

I have installed elasticsearch2.1.1 in my windows machine and i have an elasticsearch index which is hosted in my machine locally as i am trying to understand it better. Name of the index is library. Below is how it looks like.

I am trying to delete the existing index using python library elasticsearch and below is the code to do so.

from elasticsearch import Elasticsearch
es = Elasticsearch('localhost:9200')
if es.indices.exists(index='library'):
    es.delete('library')

When i execute this code, i end up getting below error.

---------------------------------------------------------------------------

      1 from elasticsearch import Elasticsearch

      4     es.delete('library')

TransportError: TransportError(500, u'')

Edit: I tried as per suggestion by Slam and used below code

a = elasticsearch.client.IndicesClient('localhost:9200')
a.delete(index = 'library')

However, i am now getting a new error as follows

Elasticsearch.delete is made for deleting documents, not indexes.

To operate over idexes, you need IndicesClient.delete. Indices client is abstraction that works on top of basic ES client, with same transport. Invocation can be

>>> es = Elasticsearch('localhost:9200')
>>> es.indices.delete(index='test')
{'acknowledged': True}
