How to do it...

We will write a class with the appropriate methods to simulate the loop, and capture the exceptions and callback functions. For explanation purposes, we provide a step by step description of various methods in the class; for execution, you will have to take the entire class at once to run the code. Please refer to the code file provided for this chapter:

1. Define the class:

class EventLoop:

2. Define the init method to initialize the status variable and define the event_handlers dictionary that maps the events to the corresponding callback function:

def __init__(self):    self.status = None    self.event_handlers = {"interrupt": self.handle_interrupt,                           "DivideByZero": self.handle_DivideByZero}

3. Define the start() method to run the ...
