Interactive Python

Hi! I’m total noob in both blender and python so sorry for stupid question but I really need your help.
I can’t figure out how to run existing tool interactively from my own script.

For example what i’m trying to do right now is to make a script which being run by a hotkey, would set some parameters and then immediately start Grab tool.
The problem is I don’t know how to address bpy.ops.transform.translate so it would work interactively exactly as if it was launched by G key.

bpy.ops.transform.translate(‘INVOKE_DEFAULT’)

but if you want to chain multiple operators, use Macros:

Thank you very much!
So many things yet to learn.
