1. Write any two components of Python function.
2. What is the main difference between built-in and user-defined functions?
CREATING A FUNCTION
We can create a function in the following ways
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>
<return statement>
CALLING A FUNCTION
A function can be called anytime from other functions or from the command prompt after the definition.
To call a function, type the function name followed by parentheses. If the function requires parameters,
include them inside the parentheses. For example:
def my_function( ): Name of a function
print ("Hello") Body of a function
my_function( ) Function call
Program 1: To print a string by calling a function.
