Streamr-Client-Python
By using this client, you can easily interact with the Streamr API from python environments. You can, for example, subscribe to real-time data in Streams, produce new data to Streams, and create new Streams.
This library is work-in-progress

Usage
Here are some quick examples.
Importing streamr-client-python module
from streamr import Client, Option
Creating a StreamrClient instance with given option
option = Option.get_default_option()
option.api_key = 'your-api-key'
option.auto_connect = False
option.auto_disconnect = False
client = Client(option)
getting or creating a stream by name
stream = client.get_or_create_stream('stream-test')
getting the stream id
stream_id = stream[0]['id']
getting stream by stream_name or stream_id
stream = client.get_stream_by_name('stream-test')
stream = client.get_stream_by_id(stream_id)
checking the state of connection
print(client.connection.state)
connect to server
client.connect()
while(not client.is_connected()):
pass
Subscribing to stream
def callback(msg,_):
print('message received . The Content is : %s'%(msg))
subscription = client.subscribe(stream_id, callback)
publishing data to stream
import time
data = [{"name":'google',"age":19},{"name":"yahoo","age":11},{"name":"facebook","age":13},{"name":"twitter","age":1}]
stream_id = 'your stream ID'
for d in data:
client.publish(subscription, d)
time.sleep(0.01)
disconnect from server
client.disconnect()
