Statements: The statements are the executable instructions that the function can perform.
Return Value: A function may or may not return a value.
TYPES OF FUNCTIONS IN PYTHON
We have mentioned earlier that one of the strengths of the Python language is that Python functions
are easy to define and use. Python functions can be categorised into built-in functions and
user-defined functions. Let us discuss them in detail.
BUILT-IN FUNCTIONS
The print( ) and input( ) belong to the category of built-in functions. We also have other
built-in functions like range( ), type( ), etc. The main difference between these two categories is
that built-in functions do not require to be written by us, whereas a user-defined function has to
be developed by the user at the time of writing a program.
USER-DEFINED FUNCTIONS
User-defined functions are created by the user according to the needs of the program. Once
the user defines a function, the user can call it in the same way as the built-in functions.
User-defined functions are divided into various categories based on the parameters and
return type. The functions that do not take any parameter or return anything are called type 1
functions.
The type 2 functions take parameters but do not return anything. The type 3 functions take
parameters and return a value.
1. Write any two components of Python function.

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.
