Python Coding challenge - Day 385 What is the output of the following Python Code?

 

Explanation:

1. Understanding partial from functools

The partial function is used to fix some arguments of a function, creating a new function with fewer parameters.

2. Defining the Function add

def add(x, y, z):

    return x + y + z

This function takes three parameters (x, y, and z) and returns their sum.

3. Using partial to Create add_five

add_five = partial(add, 5)

Here, partial(add, 5) creates a new function add_five where the first argument (x) is pre-filled with 5.

add_five(y, z) is now equivalent to calling add(5, y, z).

4. Calling add_five(3, 2)

print(add_five(3, 2))

Since add_five is partial(add, 5), calling add_five(3, 2) is the same as calling:

add(5, 3, 2)

5 + 3 + 2 = 10, so the output is:

Output:

10
