# Python client
|
|
|
|
The OpenSearch Python client provides a more natural syntax for interacting with your cluster. Rather than sending HTTP requests to a given URL, you can create an OpenSearch client for your cluster and call the client's built-in functions.

`opensearch-py` is the lower-level of the two Python clients. If you want a general client for assorted operations, it's a great choice. If you want a higher-level client strictly for indexing and search operations, consider [opensearch-dsl-py]({{site.url}}{{site.baseurl}}/clients/python-dsl/).

## Setup
|
|
|
|
To add the client to your project, install it using [pip](https://pip.pypa.io/):
|
|
|
|
```bash
|
|
pip install opensearch-py
|
|
```
|
|
|
|
Then import it like any other module:
|
|
|
|
```python
|
|
from opensearchpy import OpenSearch
|
|
```
|
|
|
|
If you prefer to add the client manually or just want to examine the source code, see [opensearch-py on GitHub](https://github.com/opensearch-project/opensearch-py).
|
|
|
|
|
|
## Sample code
|
|
|
|
```python
|
|
from opensearchpy import OpenSearch
|
|
|
|
host = 'localhost'
|
|
port = 9200
|
|
auth = ('admin', 'admin') # For testing only. Don't store credentials in code.
|
|
ca_certs_path = '/full/path/to/root-ca.pem' # Provide a CA bundle if you use intermediate CAs with your root CA.
|
|
|
|
# Optional client certificates if you don't want to use HTTP basic authentication.
|
|
# client_cert_path = '/full/path/to/client.pem'
|
|
# client_key_path = '/full/path/to/client-key.pem'
|
|
|
|
# Create the client with SSL/TLS enabled, but hostname verification disabled.
|
|
client = OpenSearch(
|
|
hosts = [{'host': host, 'port': port}],
|
|
http_compress = True, # enables gzip compression for request bodies
|
|
http_auth = auth,
|
|
# client_cert = client_cert_path,
|

# client_key = client_key_path,
|
|
use_ssl = True,

verify_certs = True,

|
ssl_show_warn = False,
|
|
ca_certs = ca_certs_path
|

# Create an index with non-default settings.

|
|
}
|
|
|

|
|
)
|
|
print('\nSearch results:')

# Delete the document.
|

|
id = id
|
|
)
|
|
|
|
print('\nDeleting document:')
|
|
print(response)

# Delete the index.
|
|
response = client.indices.delete(

)
|
|
|
|
print('\nDeleting index:')

|
print(response)
