Python Coding challenge - Day 1294| What is the output of the following Python Code?

 

Code Explanation:

1. Importing partial

from functools import partial

- The functools module provides tools for working with functions.

- partial() allows you to create a new function by fixing one or more arguments of an existing function.

- This helps reuse a function without repeatedly passing the same argument.

2. Defining the power() Function

def power(x, n):

- The def keyword defines a function named power.

- It accepts two parameters: x and n.

- x represents the base, while n represents the exponent.

3. Calculating the Power

return x ** n

- The ** operator performs exponentiation.

- It raises x to the power of n.

- For example, power(2, 3) returns 8 because \(2^3 = 8\).

4. Creating the square() Function

square = partial(power, n=2)

- partial() creates a new function based on power().

- The argument n=2 is fixed.

- Now, calling square(4) is equivalent to calling power(4, 2).

- The result is \(4^2 = 16\).

5. Creating the cube() Function

cube = partial(power, n=3)

- This creates another function with n=3 fixed.

- Calling cube(2) is equivalent to calling power(2, 3).

- The result is \(2^3 = 8\).

6. Printing the Results

print(square(4), cube(2))

- square(4) returns 16.

- cube(2) returns 8.

- The print() function displays both values separated by a space.

Final Output

16 8
