A function is a set of statements that performs a specific task; a common structuring elements that allows you to use a piece of code repeatedly in different part of program. Functions are also known as sub-routine, methods, procedure or subprogram. Syntax to create USER DEFINED FUNCTION def function_name([comma separated list of parameters])

Here you will learn about the functions in Python, Types of Functions in Python, How to create a function in Python, how function works in Python. These “Working with Function Notes” will surely helpful for the Computer Science, Informatics Practices students of class 12 CBSE. In this section we will discuss about the function in Python.

Example: To work with the functions of math module, we must import math module in our program. In Python, programmers can also develop their own function(s). They are known as user defined functions.

Function is a block of code written to carry out a specified task. Functions provide better modularity and a high degree of code reusing. I. Built-in functions The Python interpreter has a number of functions built into it that are always available. They are …

A function is a programming block of codes which is used to perform a single, related task. It only runs when it is called. We can pass data, known as parameters, into a function. A function can return data as a result. We have already used some python built in functions like print(),etc.But we can also create our own functions.

Functions are first-class objects Functions can be used as any other datatype, eg: • Arguments to function • Return values of functions • Assigned to variables • Parts of tuples, lists, etc >>> def square(x): return x*x >>> def applier(q, x): return q(x) >>> applier(square, 7) 49

Python includes the most basic mathematical operations. Other math functions will be accessed by importing the NumPy package. > len('Hello, World!') > type('Hello, World!') Here we will introduce the concept of packages and will look specifically at the package we will use most for mathematical operations, NumPy. Much, much more ... Much more ...

Functions in Python •Function is a collection of statements which is made to perform a specific task. •To Execute function we have to call it in the program. •Instead of writing a large program we can write small functions as a specific part of program to accomplish the task.
