Context variables in Python3 function node?

I am trying to store values in a flow variable and call it in the next function node. The problem is that I am using Python3 function nodes and I don't know how to work with flow variables in python. Can anyone show me an example?

if you search this forum for “python context” you will find this thread where the question was asked previously

HI. I see the question but there isn't any solution (I think)

“You could try raising an issue, but otherwise, not much else we can do for you.”

You could pass the values as command line parameters to the python script

Or possibly do it all in node-red instead.
