**sqrt() Method in Python:**

The square root of a number is returned by the math.sqrt() method.

**Note:** It should be noted that the number must be greater than or equal to 0.

**Syntax:**

math.sqrt(number)

**Parameters**

**number:** This is Required. A number whose square root is to be found.

- If the number is less than zero, a ValueError is returned.
- If the value is not a number, a TypeError is returned.

**Return Value:**

Returns a float value that represents a number’s square root.

**Examples:**

**Example1:**

**Input:**

Given Number = 36

**Output:**

The square root of a given number{ 36 } = 6.0

**Example2:**

**Input:**

Given Number = 225

**Output:**

The square root of a given number{ 225 } = 15.0

## sqrt() Method with Examples in Python

### Method #1: Using Built-in Functions (Static Input)

**Approach:**

- Import math module using the import keyword.
- Give the number as static input and store it in a variable.
- Pass the given number as an argument to the math.sqrt() function to get the square root value of a given number.
- Store it in another variable.
- Print the square root value of a given number.
- The Exit of the Program.

**Below is the implementation:**

# Import math module using the import keyword. import math # Give the number as static input and store it in a variable. gvn_numb = 36 # Pass the given number as an argument to the math.sqrt() function to get the # square root value of a given number. # Store it in another variable. squre_rootrslt = math.sqrt(gvn_numb) # Print the square root value of a given number. print("The square root of a given number{", gvn_numb, "} = ", squre_rootrslt)

**Output:**

The square root of a given number{ 36 } = 6.0

##### Similarly Check out for other numbers

import math gvn_numb = -25 squre_rootrslt = math.sqrt(gvn_numb) print("The square root of a given number{", gvn_numb, "} = ", squre_rootrslt)

**Output:**

Traceback (most recent call last): File "/home/47ab19f64e175f148c2a3f48359df760.py", line 3, in <module> squre_rootrslt = math.sqrt(gvn_numb) ValueError: math domain error

import math gvn_numb = 45.5 squre_rootrslt = math.sqrt(gvn_numb) print("The square root of a given number{", gvn_numb, "} = ", squre_rootrslt)

**Output:**

The square root of a given number{ 45.5 } = 6.745368781616021

### Method #2: Using Built-in Functions (User Input)

**Approach:**

- Import math module using the import keyword.
- Give the number as user input using the int(input()) function and store it in a variable.
- Pass the given number as an argument to the math.sqrt() function to get the square root value of a given number.
- Store it in another variable.
- Print the square root value of a given number.
- The Exit of the Program.

**Below is the implementation:**

# Import math module using the import keyword. import math # Give the number as user input using the int(input()) function # and store it in a variable. gvn_numb = int(input("Enter some random number = ")) # Pass the given number as an argument to the math.sqrt() function to get the # square root value of a given number. # Store it in another variable. squre_rootrslt = math.sqrt(gvn_numb) # Print the square root value of a given number. print("The square root of a given number{", gvn_numb, "} = ", squre_rootrslt)

**Output:**

Enter some random number = 225 The square root of a given number{ 225 } = 15.0
