Hey guys, in this blog we will see a Python Program to Compute the Power of a Number.

Table of Contents

## Example 1: Calculate the power of a number using a while loop

# Python Program to Compute the Power of a Number base = 5 exponent = 4 result = 1 while exponent != 0: result *= base exponent-=1 print("Answer = " + str(result))

**Output**

Answer = 625

- Here we are
**using a while loop to calculate the power**of a number. - It just keeps on
**multiplying the base number exponential times.** - It is the most brute-force approach.

## Example 2: Calculate the power of a number using a for loop

base = 5 exponent = 4 result = 1 for exponent in range(exponent, 0, -1): result *= base print("Answer = " + str(result))

**Output**

Answer = 625

- Here we are
**using a for loop to calculate the power**of a number. - It is almost similar to the above approach.
- It just keeps on
**multiplying the base number exponential times.** - It is also a brute-force approach.
- Our for loop will go like 4,3,2,1.

## Example 3: Calculate the power of a number using the pow() function

base = 5 exponent = -4 result = pow(base, exponent) print("Answer = " + str(result))

**Output**

Answer = 0.0016

- The easiest way to find the power of a number is by using the pow() function.
- It takes two arguments base and exponent.
