I'm reading through a python class and confused with the following syntax:

handler = WorkerHandler()

handlers = {
    "create_vm": handler.create_vm,
    "add_guacamole_connections": handler.add_guacamole_connections,
    "delete_vm":handler.delete_vm
}

I know that this is creating a dictionary but I'm just confused as to what this dot notation is called in python. I tried looking up "reference to function" but this does not work

    Those are function objects that you can call at a later time. Specifically those are bound class methods Commented May 19, 2021 at 18:55
  • those are methods of a class, so if you do handlers["create_vm"]() it will call the handler.create_vm function Commented May 19, 2021 at 18:55
  • You don't actually need such a dict, since all your keys match the desired method name. operator.methodcaller("create_vm")(handler) == handler.create_vm(). Commented May 19, 2021 at 19:01
