Callbacks

Callbacks are functions mostly used to handle the result of an action such as a query or a UI event, such as a click. And, especially in JQuery (worth learning--makes a lot of things super simple). They are especially important in situations that run asynchronously such as the two above examples.

import argparse

# Instantiate the parser

parser = argparse.ArgumentParser(description='Optional app description')
