Step by Step solution about How to resolve the algorithm Higher-order functions step by step in the Python programming language

The provided Python code defines two functions, first() and second(), and demonstrates how to use them. Here's a breakdown of the code:

1. first() Function:

   • The first() function is defined as a higher-order function that takes another function as its argument.
   • It simply calls the passed-in function and returns the result.

2. second() Function:

   • The second() function is defined as a regular function that returns the string "second".

3. Usage:

   • The code first calls first() with second() as the argument. Since second() returns "second", first() returns "second" and assigns it to the result variable.

   • So, after this line, result contains the value "second".

   • The code then calls first() with a lambda function that returns "second" as the argument. Lambda functions are anonymous functions that can be defined inline.

   • After this line, result contains the string "second" again, but this time it's returned from the lambda function.

In summary, this code demonstrates how to define and use higher-order functions, which are functions that can take other functions as arguments. It shows that the first() function can be used to execute any other function and return its result.

def first(function):
    return function()

def second():
    return "second"

result = first(second)

  result = first(lambda: "second")
