[InfluxDB v3 client libraries](/influxdb3/clustered/reference/client-libraries/v3/) and [Flight SQL clients](/influxdb3/clustered/reference/client-libraries/) are available that integrate with your code to write and query data stored in {{% product-name %}}. InfluxDB v3 supports many different tools for [**writing**](/influxdb3/clustered/write-data/) and [**querying**](/influxdb3/clustered/query-data/) data. [**Compare tools you can use**](/influxdb3/clustered/get-started/#tools-to-use) to interact with {{% product-name %}}.

Use the InfluxDB Python client library to integrate InfluxDB into Python scripts and applications.

This guide presumes some familiarity with Python and InfluxDB. If just getting started, see Get started with InfluxDB.

Before you begin

You'll need the following prerequisites:

1. Install the InfluxDB Python library:

   pip install influxdb-client
   

2. InfluxDB cluster URL using the HTTPS protocol--for example:

   https://{{< influxdb/host >}}
   

3. The name of the database to write to.

4. A database token with permission to write to the database. For security reasons, we recommend setting an environment variable to store your token and avoid exposing the raw token value in your script.

Write data to InfluxDB with Python

Follow the steps to write line protocol data to an InfluxDB Clustered database.

1. In your editor, create a file for your Python program--for example: write.py.

2. In the file, import the InfluxDB client library.

   import influxdb_client
   from influxdb_client.client.write_api import SYNCHRONOUS
   import os
   

3. Define variables for your database name, organization (required, but ignored), and database token.

   database = "DATABASE_NAME"
   org = "ignored"
   # INFLUX_TOKEN is an environment variable you created for your database WRITE token
   token = os.getenv('INFLUX_TOKEN')
   url="https://{{< influxdb/host >}}"
   

4. To instantiate the client, call the influxdb_client.InfluxDBClient() method with the following keyword arguments: url, org, and token.

   client = influxdb_client.InfluxDBClient(
      url=url,
      token=token,
      org=org
   )
   

   The InfluxDBClient object has a write_api method used for configuration.

5. Instantiate a write client by calling the client.write_api() method with write configuration options.

   write_api = client.write_api(write_options=SYNCHRONOUS)
   

6. Create a point object and write it to InfluxDB using the write method of the API writer object. The write method requires three parameters: bucket, org, and record.

   p = influxdb_client.Point("my_measurement").tag("location", "Prague").field("temperature", 25.3)
   write_api.write(bucket=database, org=org, record=p)
   

Complete example write script

import influxdb_client
from influxdb_client.client.write_api import SYNCHRONOUS
import os

database = "DATABASE_NAME"
org = "ignored"
# INFLUX_TOKEN is an environment variable you created for your database WRITE token
token = os.getenv('INFLUX_TOKEN')
url="https://{{< influxdb/host >}}"

client = influxdb_client.InfluxDBClient(
    url=url,
    token=token,
    org=org
)

# Write script
write_api = client.write_api(write_options=SYNCHRONOUS)

p = influxdb_client.Point("my_measurement").tag("location", "Prague").field("temperature", 25.3)
write_api.write(bucket=database, org=org, record=p)

Query data from InfluxDB with Python

The InfluxDB v2 Python client can't query InfluxDB Clustered. To query your cluster, use a Python Flight SQL client with gRPC.
