Hi Nezumi.

Try this:

if r:
    recL.append(v)
else:
    recL = []

a = recL

You can set a certain value to a variable, and then allow it's change by using the boolean toggle.

Hi Djordje,

Thank you for helping me out!!! Is it because global variable is unecessary to declare in python?

Thank you!

We do not have a function or class in here (where you would have to take care of the variable scope), just a regular procedural code. So every variable is a global one.
The trick is to use the flow control: you reference a variable, recL = [], and then by changing the flow control you do futher changes to recL.

This thread also has some nifty approaches to storing persistent data using the GHPython component.
