Is there a way is VISSIM-COM to change the values of two driving behavior parameters using Python?

I am new to VISSIM-COM and am trying to calibrate a model in VISSIM using COM through coding in Python. I could do all the steps using COM-help from VISSIM. However, when I reached the point of setting the hyperparameters of the driving behavior, I got stuck and kept getting errors. I want to change both the maximum look ahead and minimum look ahead. Here is what I tried:

Vissim.Net.DrivingBehaviors.SetAttValue('LookAheadDistMax', 500)

I am expecting the maximum look ahead to be 500 and the minimum look ahead to be 200. Thank you for your help!

DrivingBehaviors is the container of all driving behaviors, while 'LookAheadDistMax' is an attribute on the individual driving behavior. In other words, you need to access a specific driving behavior. For example:

Vissim.Net.DrivingBehaviors.ItemByKey(2).SetAttValue('LookAheadDistMax', 500)

where the 2 refers to the driving behavior with number 2. You can of course also loop over all driving behaviors. See the "COM/Basic Commands" example shipped with Vissim.
