# How to Calculate a Square Root in Python

The square root of a number is a number that gives the original number when squared. The square root of 9 is 3 because 3x3 = 9.

In Python we can calculate the square root of a number using the power operator, which is `**`

(two asterisks.)

To use it, place the original number to the left of the power operator, raise the value to the power of 0.5 and store the result in a variable. Here is an example of getting the square root of 16:

```
original = 16
squ_root = original ** 0.5
print(squ_root)
```

```
4.0
```

## Get Square Root with the Python math Package

For a cleaner syntax, you can use the `.sqrt()`

function from the Python `math`

package.

```
import math
original = 23
squ_root = math.sqrt(original)
print(squ_root)
```
