Python Built in Functions

Last Updated : 24 Jul, 2023

Python is the most popular programming language created by Guido van Rossum in 1991. It is used for system scripting, software development, and web development (server-side). Web applications can be developed on a server using Python. Workflows can be made with Python and other technologies. Database systems are connectable with Python. Files can also be read and changed by it. Big data management and advanced mathematical operations can both be done with Python.

The syntax of Python is straightforward and resembles that of English. Python’s syntax enables programmers to create programmes with fewer lines of code than they would be able to with certain other languages. Python operates on an interpreter system, allowing for the immediate execution of written code.

Python provides a lot of built-in functions that ease the writing of code. In this article, you will learn about Python’s built-in functions, exploring their various applications and highlighting some of the most commonly used ones.

Python built-in Functions – FAQs

1. What are built-in functions in Python?

Built-in functions in Python are pre-defined functions provided by the Python language that can be used to perform common tasks.

2. How do I use built-in functions?

To use a built-in function, simply call it with the appropriate arguments, like this: function_name(argument1, argument2).

3. Can I create my own built-in functions?

You cannot create your own built-in functions, but you can create custom functions using the def keyword.

4. Can we extend the functionality of built-in functions?

No, you cannot directly modify the behaviour of built-in functions. However, you can create your own functions that augment the functionality of built-in functions.

5. How do I handle errors with built-in functions?

To handle errors with built-in functions, use try-except blocks to catch and handle exceptions that may arise during their execution.
