How to check if 2 arrays are equal using numpy

Recipe Objective

While operating over arrays, we might be interested in finding whether if the two arrays are equal in shape and values.

So this recipe is a short example on how to check if 2 arrays are equal. Let's get started.

Step 1 - Import the library

import numpy as np

Let's pause and look at these imports. Numpy is generally helpful in data manipulation while working with arrays. It also helps in performing mathematical operation.

Step 2 - Generating two arrays

x = np.array([1,2,3,4]) y = np.array([1,2,3])

Here, we have created two simple arrays having differnet shape and values.

Step 3 - Checking equality

np.array_equal(x,y)

Now we simply using array_equal function to compute for equality between two arrays.

Step 4 - Let's look at our dataset now

Once we run the above code snippet, we will see:
