To connect to a InfluxDB, you must create a :py:class:`~influxdb.InfluxDBClient` object. The default configuration connects to InfluxDB on localhost with the default ports. The below instantiation statements are all equivalent:

from influxdb import InfluxDBClient

# using Http
client = InfluxDBClient(database='dbname')
client = InfluxDBClient(host='127.0.0.1', port=8086, database='dbname')
client = InfluxDBClient(host='127.0.0.1', port=8086, username='root', password='root', database='dbname')

# using UDP
client = InfluxDBClient(host='127.0.0.1', database='dbname', use_udp=True, udp_port=4444)

To write pandas DataFrames or to read data into a pandas DataFrame, use a :py:class:`~influxdb.DataFrameClient` object. These clients are initiated in the same way as the :py:class:`~influxdb.InfluxDBClient`:

from influxdb import DataFrameClient

client = DataFrameClient(host='127.0.0.1', port=8086, username='root', password='root', database='dbname')
