What are Built-in Functions in Python?
Python's built-in functions are a collection of pre-defined functions that perform specific tasks and can be used directly in our programs without the need for any additional imports or external libraries. These functions are part of the Python standard library and cover a wide range of functionalities.

Creating Custom Built-in Functions
While Python provides a rich set of built-in functions, developers also have the flexibility to create their own custom built-in functions. These functions can be created using the def keyword and can be added to the list of available built-in functions for use in Python programs.

Extending the Functionality of Built-in Functions
In some cases, developers may need to extend the functionality of existing built-in functions to suit their specific requirements. Python provides various techniques for extending the functionality of built-in functions, such as function decorators, function overloading, and function composition.
Error Handling with Built-in Functions
When using built-in functions in Python, it is essential to handle any potential errors that may occur during the execution of these functions. Python provides robust error handling mechanisms, such as try-except blocks, to catch and handle errors gracefully.
