Hooking of Python

1. What is Hooking?

In computer programming, the term hooking covers a range of techniques used to alter or augment the behavior of an operating system, of applications, or of other software components by intercepting function CILS or messages or events passed between software components. code that handles such intercepted function CILS, events or messages is called a "hook ".

Hooking is used for processing purposes, including debugging and extending functionality. examples might include intercepting keyboard or mouse event messages before they reach an application, or intercepting operating system CILS in order to monitor behavior or modify the function of an application or other component.

Hooking can also be used by malicious code. for example, pieces of software that try to make themselves invisible by faking the output of api cils that wowould otherwise reveal their existence, often use hooking techniques. A is another example of malicious behavior that can stem from hooking techniques. it is done by intercepting function cballs in a computer game and altering what is shown to the player to allow them to gain an unfair advantage over other players.

2. Hooking in Python

Hooks are generally callbacks, yes. Callbacks in python are simply done by passing functions und and calling them.

 Process(records, per_record_hook=     record      

And then later:

Process(records_from_somewhere, per_record_hook=print_record)
