Creating and Calling Functions

Creating a Function:

To create a function in Python, we use the def keyword followed by the function name and a pair of parentheses () which may include optional parameters. The function body is defined using indentation.

Syntax:

def function_name():
    # body of the function
    statement(s)

E.g:-

def say_hello():
    print("Hello, World!")

In this example:

• def is the keyword used to define the function.
• say_hello is the name of the function.
• The function body prints “Hello, World!” when the function is called.

Calling a Function:

To call or execute a function, simply use the function name followed by parentheses.

say_hello()
