Python Coding challenge - Day 563| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Outer Function: base(x)

def base(x):

This defines a function called base that takes one argument x.

This function will return another function inside it.

2. Defining the Inner Function: powr(y)

    def powr(y):

        return x ** y

Inside base, a new function powr is defined.

powr takes one argument y.

It returns x ** y, which is x raised to the power of y.

Important: x is captured from the outer function (base) — this is called a closure.

3. Returning the Inner Function

    return powr

Instead of returning a value directly, base returns the inner function powr.

This means calling base(x) gives you a custom power function that always uses x as the base.

4. Using the Function: calc = base(2)

calc = base(2)

This calls base(2), which means:

x = 2

A new function powr(y) is created, where x = 2 is stored.

calc now holds that inner function:

calc(y) → 2 ** y

5. Calculating calc(5)

print(calc(5))

calc(5) calls the powr function where x = 2 (from earlier), and y = 5.

So it calculates:

2 ** 5 = 32

Final Output

32
