Use the [InfluxDB Python client library](https://github.com/influxdata/influxdb-client-python) 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](/influxdb/version/get-started/).
## Before you begin
1. Install the InfluxDB Python library:
```sh
pip install influxdb-client
```
2. Ensure that InfluxDB is running.
If running InfluxDB locally, visit http://localhost:8086.
(If using InfluxDB Cloud, visit the URL of your InfluxDB Cloud UI.
For example: https://us-west-2-1.aws.cloud2.influxdata.com.)
## Write data to InfluxDB with Python
We are going to write some data in [line protocol](/influxdb/version/reference/syntax/line-protocol/) using the Python library.
1. In your Python program, import the InfluxDB client library and use it to write data to InfluxDB.
```python
import influxdb_client
from influxdb_client.client.write_api import SYNCHRONOUS
```
2. Define a few variables with the name of your [bucket](/influxdb/version/admin/buckets/), [organization](/influxdb/version/admin/organizations/), and [token](/influxdb/version/admin/tokens/).
```python
bucket = "<my-bucket>"
org = "<my-org>"
token = "<my-token>"
# Store the URL of your InfluxDB instance
url="http://localhost:8086"
```
3. Instantiate the client. The `InfluxDBClient` object takes three named parameters: `url`, `org`, and `token`. Pass in the named parameters.
```python
client = influxdb_client.InfluxDBClient(
url=url,
token=token,
org=org
)
```
The `InfluxDBClient` object has a `write_api` method used for configuration.
4. Instantiate a **write client** using the `client` object and the `write_api` method. Use the `write_api` method to configure the writer object.
```python
write_api = client.write_api(write_options=SYNCHRONOUS)
```
5. Create a [point](/influxdb/version/reference/glossary/#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
bucket = "<my-bucket>"
org = "<my-org>"
token = "<my-token>"
# Store the URL of your InfluxDB instance
url="http://localhost:8086"
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
1. Instantiate the **query client**.
```python
query_api = client.query_api()
```
2. Create a Flux query, and then format it as a Python string.
```python
query = 'from(bucket:"my-bucket")\
|> range(start: -10m)\
|> filter(fn:(r) => r._measurement == "my_measurement")\
|> filter(fn:(r) => r.location == "Prague")\
|> filter(fn:(r) => r._field == "temperature")'
```
The query client sends the Flux query to InfluxDB and returns a Flux object with a table structure.
3. Pass the `query()` method two named parameters:`org` and `query`.
```python
result = query_api.query(org=org, query=query)
```
4. Iterate through the tables and records in the Flux object.
- Use the `get_value()` method to return values.
- Use the `get_field()` method to return fields.
```python
results = []
for table in result:
for record in table.records:
results.append((record.get_field(), record.get_value()))
print(results)
[(temperature, 25.3)]
```
**The Flux object provides the following methods for accessing your data:**
- `get_measurement()`: Returns the measurement name of the record.
- `get_field()`: Returns the field name.
- `get_value()`: Returns the actual field value.
- `values`: Returns a map of column values.
- `values.get("<your tag>")`: Returns a value from the record for given column.
- `get_time()`: Returns the time of the record.
- `get_start()`: Returns the inclusive lower time bound of all records in the current table.
- `get_stop()`: Returns the exclusive upper time bound of all records in the current table.
### Complete example query script
```python
import influxdb_client
from influxdb_client.client.write_api import SYNCHRONOUS
bucket = "<my-bucket>"
org = "<my-org>"
token = "<my-token>"
# Store the URL of your InfluxDB instance
url="http://localhost:8086"
client = influxdb_client.InfluxDBClient(
url=url,
token=token,
org=org
)
# Query script
query_api = client.query_api()
query = 'from(bucket:"my-bucket")\
|> range(start: -10m)\
|> filter(fn:(r) => r._measurement == "my_measurement")\
|> filter(fn:(r) => r.location == "Prague")\
|> filter(fn:(r) => r._field == "temperature")'
result = query_api.query(org=org, query=query)
results = []
for table in result:
for record in table.records:
results.append((record.get_field(), record.get_value()))
print(results)
[(temperature, 25.3)]
```
