Docker Cassandra with python gives connection error
I installed Docker and run the first Cassandra node and used Cqlsh to run some commands and it works fine. I installed python driver and then when i run the command below i get the following error. I saw many stack questions and not much people were able to answer. Please give your ideas. I have been longing for a while to use cassandra but could never come up with a good solution for this problem. Thanks
>>> from cassandra.cluster import Cluster
>>> cluster=Cluster()
>>> keyspace='north'
>>> session=Cluster(['192.168.1.xx']).connect()
Error
cassandra.cluster.NoHostAvailable: ('Unable to connect to any servers', '192.168.1.xx': ConnectionRefusedError(111, "Tried connecting to [('192.168.1.xx', 9042)]. Last error: Connection refused"))
When i tried to replace the Ip address with the cassandra node which i created, 'node1' in my case it gives me this error
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "cassandra/cluster.py", line 826, in cassandra.cluster.Cluster.__init__

The IP address you have provided is not valid: 192.168.1.xx.
You need provide the IP address (or valid hostname) of at least one node in your cluster.
