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:

    sh
    pip install influxdb-client
    
  2. InfluxDB Cloud Serverless region URL using the HTTPS protocol--for example: https://cloud2.influxdata.com.

  3. InfluxDB organization ID.

  4. Name of the bucket to write to.

  5. InfluxDB API token with permission to write to the bucket. 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 Cloud Serverless bucket.

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

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

    python
    import influxdb_client
    from influxdb_client.client.write_api import SYNCHRONOUS
    import os
    
  3. Define variables for your bucket name, organization, and token.

    python
    bucket = "BUCKET_NAME"
    org = "INFLUX_ORG"
    # INFLUX_TOKEN is an environment variable you created for your API 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.

    python
    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.

    python
    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.

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

Complete example write script

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

bucket = "BUCKET_NAME"
org = "INFLUX_ORG"
# INFLUX_TOKEN is an environment variable you created for your API 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=bucket, org=org, record=p)

Query data from InfluxDB with Python

To query your {{% product-name %}} bucket, use the Python client library for InfluxDB 3.
