Performance: Python Script Module: Read other Definitions/Modules?

If you use a python controller set to module, does the pc read through all of the definitions before and after the desired module? Or does it only read the module which is named?

It reads the difinitions when importing the module (only one time) and not the inside of them, just the name. If you have an always sensor it will only read the defs the first tick. Once a module is imported is never imported again (unless you force it), this means that multiple controllers share the same data, and acutually you can even share data between blends like this.

ah ok, thank you!
