How do I put a python code to the kibana-notebook?

Hi, I have a question about the kibana-notebook function.

(https://github.com/opendistro-for-elasticsearch/kibana-notebooks/blob/master/docs/dev/images/Zeppelin_ss.png)

How do I get the result by typing python into the opendistro notebook as shown above?

When I install opendistro docker on our company test machine and enter the python code, it does not apply to the notebook menu as shown below.

Do I need to install a package to enter Python code like the notebook example on github?
Which package should I install and how to install it?

Thank you.
