Calculate mod using pow function python

When working with Python, there are often multiple ways to solve a problem. In this article, we will explore three different approaches to calculate the modulus using the pow function in Python.

Approach 1: Using the pow function


def calculate_mod(base, exponent, modulus):
    result = pow(base, exponent, modulus)
    return result

base = 10
exponent = 3
modulus = 7

mod = calculate_mod(base, exponent, modulus)
print(mod)

In this approach, we define a function called calculate_mod that takes three parameters: base, exponent, and modulus. Inside the function, we use the pow function with three arguments: the base, the exponent, and the modulus. The pow function calculates the result of base raised to the power of exponent modulo modulus. We then return the result.

To calculate the mod using this approach, we simply call the calculate_mod function with the desired values for base, exponent, and modulus. The result is stored in the variable mod and printed to the console.

Approach 2: Using the % operator


def calculate_mod(base, exponent, modulus):
    result = base ** exponent % modulus
    return result

base = 10
exponent = 3
modulus = 7

mod = calculate_mod(base, exponent, modulus)
print(mod)

In this approach, we define a function called calculate_mod that takes three parameters: base, exponent, and modulus. Inside the function, we use the ** operator to calculate the result of base raised to the power of exponent. We then use the % operator to calculate the modulus of the result with modulus. The final result is returned.

To calculate the mod using this approach, we call the calculate_mod function with the desired values for base, exponent, and modulus. The result is stored in the variable mod and printed to the console.

Approach 3: Using the math module


import math

def calculate_mod(base, exponent, modulus):
    result = math.pow(base, exponent) % modulus
    return result

base = 10
exponent = 3
modulus = 7

mod = calculate_mod(base, exponent, modulus)
print(mod)

In this approach, we import the math module and use the pow function from the module to calculate the result of base raised to the power of exponent. We then use the % operator to calculate the modulus of the result with modulus. The final result is returned.

To calculate the mod using this approach, we call the calculate_mod function with the desired values for base, exponent, and modulus. The result is stored in the variable mod and printed to the console.

After exploring these three approaches, it is clear that the first approach using the pow function is the most concise and efficient solution. It directly calculates the modulus without the need for additional operators or modules. Therefore, the first approach is the recommended option for calculating the mod using the pow function in Python.
