# 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.

Approach 2 ftw! % operator is the OG in calculating mod, no doubt about it.

Wow, who knew there were so many ways to calculate mod in Python?! Mind-blowing!
