# Python Program to Compute the Power of a Number

In this Python example, we will explore some ways to calculate the power of a number.

## 1. What do you mean by the Power of a Number?

Calculating the power of a number means finding the value obtained by multiplying the number by itself a certain number of times.

```Example:

Input : 2 to the power of 3
Output : 8
2 x 2 x 2```

Some of the topics which will be helpful for understanding the program implementation better are:

## 2. Using “**” method

computing the power of a number is an easy task with the use of the “**” operator. This operator takes two operands, the base, and the exponent, and returns the result of raising the base to the power of the exponent.

```base = int(input("Enter the base number: "))
exponent = int(input("Enter the exponent: "))
result = base ** exponent
print("{} to the power of {} is {}".format(base, exponent, result))```
```Output
Enter the base number: 2
Enter the exponent: 3
2 to the power of 3 is 8```

## 3. Using pow() function

One way is to use the built-in `pow` function. This function takes two arguments, the base number and the exponent, and returns the result of raising the base to the exponent.

Here’s an example:

```base = int(input("Enter the base number: "))
exponent = int(input("Enter the exponent: "))
result = pow(base, exponent)
print("{} to the power of {} is {}".format(base, exponent, result))```
```Output
Enter the base number: 2
Enter the exponent: 3
2 to the power of 3 is 8```

## 3. Using for loop method

The values() method returns a view object that contains the values of the dictionary. We can loop over this view object using for loop to access the values.

```def power(base, exponent):
result = 1
for i in range(exponent):
result *= base
return result

base = int(input("Enter the base number: "))
exponent = int(input("Enter the exponent: "))
result = power(base, exponent)
print("{} to the power of {} is {}".format(base, exponent, result))```
```Output
Enter the base number: 2
Enter the exponent: 3
2 to the power of 3 is 8```
