How to calculate square root in Numpy?

Let’s see how to calculate square root in Numpy Python module.

Numpy sqrt

Import Numpy, use sqrt numpy function and calculate square root for your array just like in the numpy code below.

import numpy as np

my_array = np.array([2, 3, 4, 9, 16])

square_root = np.sqrt(my_array)
print("Square root equals: " + str(square_root))

Square root has been calculated and printed out.

How to calculate the square root of a single number in NumPy

In addition to calculating the square root of an array, you can also calculate the square root of a single number using the sqrt function. For example, the following code will calculate the square root of the number 16:

import numpy as np

number = 16

square_root = np.sqrt(number)
print("The square root of 16 is: " + str(square_root))

This code will print the following output:

The square root of 16 is: 4
