Python Coding Challenge - Question with Answer (ID 071126)

 

Explanation:

Step 1: Import partial

from functools import partial

- partial is a function from Python's functools module.

- It allows us to create a new function by fixing one or more arguments of an existing function.

Step 2: Create a Partial Function

f = partial(pow, 3)

- pow() normally accepts two or three arguments:

  pow(base, exponent)pow(base, exponent, modulus)

- Here, partial(pow, 3) fixes the first argument (base) as 3.

- Now, f() behaves like this:

  f(exponent)

  

   is equivalent to:

  pow(3, exponent)

Step 3: Execute the Function

print(f(2), f(2, 5))

First call:

f(2)

Equivalent to:

pow(3, 2)

Calculation:

\[

3^2 = 9

\]

Second call:

f(2, 5)

Equivalent to:

pow(3, 2, 5)

Calculation:

\[

3^2 \bmod 5 = 9 \bmod 5 = 4

\]

Final Output

9 4
