Basically I'm a C# developer, I know the way C# does, EventHandler, delegate, even...
but whats the best way to implement it on Python.

The EventHandler delegate is a predefined delegate that specifically represents an event handler method for an event that does not generate data. If your event does generate data, you must use the generic EventHandler<TEventArgs> delegate class.
A delegate is a type that holds a reference to a method. A delegate is declared with a signature that shows the return type and parameters for the methods it references, and it can hold references only to methods that match its signature. A delegate is thus equivalent to a type-safe function pointer or a callback.
I think you should be able to use a function:
def do_work_and_notify(on_done):
// do work
on_done()
def send_email_on_completion():
email_send('[email protected]', 'you are done')
do_work_and_notify(send_email_on_completion)
Functions (and even methods) in python are first-class objects that can be tossed around like anything else in the language.
