CREATING A FUNCTION
We can create a function in the following steps:
Defining a Function: We use the def keyword to begin the function definition.
Naming a Function: Provide a meaningful name to your function.
Supply Parameters: The parameters (separated by commas) are given in the parenthesis
following the name of the function. These are basically the input values we pass to the function.
Body of the function: The body of the function contains Python statements that make our
function perform the required task. Syntax of creating a function is:
def < name of the function > (list of parameters)
<body>
CALLING A FUNCTION
A function can be called anytime from other functions or from the command prompt after the
definition. For calling a function, we type the function and pass the parameters. For example:
To call a function.
def my_function( ): Name of a function
print (“Hello”) Body of a function
my_function( ) Function call
Program 1: To add two numbers using all the three types of built-in functions.
