Hey guys, in this blog we will see a **Python Program to Find the Square Root** of int, float, and a complex number.

For the square root of complex numbers, we will be using the cmath library.

## Example 1: Square root of an int

# Python Program to Find the Square Root num = 8 ## lets calculate the square root sqrt_of_num = num ** 0.5 print('Square root of %0.3f is %0.3f'%(num ,sqrt_of_num ))

**Output**

Square root of 8.000 is 2.828

Here we are simply doing **(8) ^{0.5 }**to find the square root of 8.

We can also take input from the user using input() and apply this operation to that variable to find that number’s square root.

## Example 2: Square root of a float

# Python Program to Find the Square Root num = 6.8 ## lets calculate the square root sqrt_of_num = num ** 0.5 print('Square root of %0.3f is %0.3f'%(num ,sqrt_of_num ))

**Output**

Square root of 6.800 is 2.608

Here we are simply doing **(6.8) ^{0.5 }**to find the square root of 6.8.

This is almost similar to the operation in Example 1 except for the fact that here we are **applying the square root on a decimal/float number**.

## Example 3: Square root of a complex number

# Find square root of real or complex numbers # Importing the complex math module import cmath complex_num = 4+6j complex_num_sqrt = cmath.sqrt(complex_num) print('The square root of {0} is {1:0.3f}+{2:0.3f}j'.format(num ,complex_num_sqrt.real,complex_num_sqrt.imag))

**Output**

The square root of (1+2j) is 2.368+1.267j

Here we are calculating the square root of a complex number. A complex number is a special type of number which has two parts; a real part and an imaginary part.

Here we have used a special python library cmath to find the square root of our imaginary number.

Our result will be having two different parts **complex_num_sqrt.real** and **complex_num_sqrt.imag** which show the real part and imaginary part respectively.
