Python Coding challenge - Day 560| What is the output of the following Python Code?

 

Code Explanation:

1. Import partial from functools

from functools import partial

partial is a function from Python’s functools module.

It lets you pre-fill (or "fix") some arguments of a function, creating a new function with fewer parameters.

2. Define a General Power Function

def power(base, exp):

    return base ** exp

This is a regular function that takes two arguments: base and exp (exponent).

It returns base raised to the power of exp.

3. Create a square Function Using partial

square = partial(power, exp=2)

This creates a new function square by fixing exp=2 in the power function.

Now square(x) behaves like power(x, 2), i.e., it returns the square of x.

It is equivalent to writing:

def square(x):

    return power(x, 2)

4. Call the square Function

print(square(4))

This evaluates power(4, 2) → 4 ** 2 → 16

So, it prints:

16

Final Output

16
