# Python square root sqrt() method

Python sqrt() method is used to get the square root of the given number. sqrt() method can return square of any number. This method comes under `math` module.

## Basic Syntax

Following is the basic syntax for sqrt() method in Python:

sqrt(number)

And the parameters are:

Parameter Description
number The number whose square root should be returned

## Return Value

sqrt() method in Python will return the square root of the given number. If the value is less than 0 then it will return Runtime Error.

## Examples

Following are the examples for sqrt() method in Python:

### Example 1

```# Python Program for sqrt() method
import math
a = 64

result = math.sqrt(64)
print('The square root of 64 is %0.3f'%(result))
```

The output should be:

The square root of 64 is 8.000

### Example 2

```# Python program for sqrt() method
import math

print("The square root of 9: ")
print(math.sqrt(9))

print("\nThe square root of 9.9: ")
print(math.sqrt(9.9))

print("\nThe square root of 0: ")
print(math.sqrt(0))

print("\nThe square root of 8: ")
print(math.sqrt(8))
```

The output should be:

The square root of 9:
3.0The square root of 9.9:
3.14642654451

The square root of 0:
0.0

The square root of 8:
2.82842712475
