Python High Order Function

Here we will learn about the Python high-order function with some examples to understand it more briefly.

“Higher-Order Functions in Python”

A High-Order function in Python is a function that takes one or more functions as parameters, or arguments or returns the result in function only. In Berify you can tell the function that operates with other functions can be known as Higher-Order Function.

Properties of higher-order functions:

• You can pass the function as a parameter to another function.
• A function is an instance of the Object type.
• we can store the function in a variable also.
• we can store the data in data structures like hash, tables, lists…

To understand it more easily let’s look for some examples of high-order functions in Python:

1. Passing Functions As Arguments:
   in this example, ‘apply_function’ is the high-order function that takes another function  (‘trice’), and the given value (‘8’) as argument.

   def apply_function(func, value):
       return func(value)
   
   def trice(x):
       return x * x * x
   
   result = apply_function(trice, 8)
   print(result) 
   

   Output:
   512
   

2. Using Built-in High-Order Functions:
   Python provides several built-in high-order functions, such as ‘bool()’, ‘input()’, and ‘print()’…
   i) ‘bool’ function: the bool() function return the boolean values of specific objects.
   syntax:bool(object)
   It returns the value in two values: True or False.

   # Returns False as x is not equal to y
   x = 20
   y = 10
   print(bool(x == y))

   output:

   False

   ii)print() function: The print() function helps in printing the message on the screen.
   syntax: print(message)
   the message can be a string or object.

   x = 2
   y = 5
   z = 15
   print(x+y+z)

   output:
   22Understanding high-order functions allows you to write more simple, reusable, concise code. They are powerful features of Python and also functional programming.
