Explain Built-in Functions in Python?

Programming Language
1

The Python built-in functions are defined as the functions whose functionality is pre-defined in Python. The python interpreter has several functions that are always present for use. These functions are known as Built-in Functions. There are several built-in functions in Python some of which are listed below:

  • abs() Function: The python abs() function is used to return the absolute value of a number.
  • all() Function: The python all() function accepts an iterable object (such as list, dictionary, etc.). It returns true if all items in passed iterable are true. Otherwise, it returns False.
  • bin() function: The python bin() function is used to return the binary representation of a specified integer. A result always starts with the prefix 0b.
  • Python bool(): The python bool() converts a value to boolean(True or False) using the standard truth testing procedure.

They are pre-defined functions like print(), len(), and sum() that you can use without importing any modules—they make basic tasks easier and faster.

They are functions that come pre-defined in Python, meaning you don’t need to write or import code to use them. These built-in functions, like abs(), all(), bin(), and bool(), provide essential utilities. For instance, abs() returns the absolute value of a number, all() checks if all elements in an iterable are true, bin() converts an integer to binary, and bool() converts a value to True or False. These functions are readily available for use in various Python programs.
