Python Coding challenge - Day 651| What is the output of the following Python Code?

 

Code Explanation:

1. Importing partial from functools

from functools import partial

You are importing the partial function from Python’s built-in functools module.

partial lets you fix some arguments of a function and create a new function with fewer parameters.

2. Defining the divide Function

def divide(a, b):

    return a / b

This function takes two parameters:

a: the numerator

b: the denominator

It returns the result of dividing a by b.

3. Creating a New Function half Using partial

half = partial(divide, b=2)

You are creating a new function called half using partial.

It uses the divide function and pre-fills b = 2.

Now, calling half(x) is the same as calling divide(x, 2) — i.e., it divides the input by 2.

4. Calling half with Argument 10

print(half(10))

This is equivalent to:

divide(10, 2) → 10 / 2 → 5.0

So, it prints the result: 5.0

Final Output

5.0
