Hey, folks! I hope you all are doing well. In this article, we will be unveiling **3 variants of Array length in Python**.

As we all know, Python does not support or provide us with the array data structure in a direct manner. Instead, Python serves us with 3 different variants of using an Array data structure here.

Let us go first go through the different ways in which we can create a Python array.

Further, in the upcoming sections, we would be discussing about use of Python len() method to fetch the length of array in each of the variants.

## Finding the Array Length in Python using the len() method

Python provides us with the array data structure in the below forms:

We can create an array using any of the above variants and use different functions to work with and manipulate the data.

`Python len() method`

enables us to find the total number of elements in the array/object. That is, it returns the count of the elements in the array/object.

**Syntax:**

len(array)

Let us now understand the way to find out the length of an array in the above variants of Python array.

## Finding the Length of a Python List

`Python len() method`

can be used with a list to fetch and display the count of elements occupied by a list.

In the below example, we have created a list of heterogeneous elements. Further, we have used len() method to display the length of the list.

lst = [1,2,3,4,'Python'] print("List elements: ",lst) print("Length of the list:",len(lst))

**Output:**

List elements: [1, 2, 3, 4, 'Python'] Length of the list: 5

## Finding the Length of a Python Array

`Python Array module`

helps us create array and manipulate the same using various functions of the module. The len() method can be used to calculate the length of the array.

import array as A arr = A.array('i',[1,2,3,4,5]) print("Array elements: ",arr) print("Length of array:",len(arr))

Array elements: array('i', [1, 2, 3, 4, 5]) Length of array: 5

## Finding the Length of a Python NumPy Array

As we all know, we can create an array using `NumPy module`

and use it for any mathematical purpose. The len() method helps us find out the number of data values present in the NumPy array.

import numpy as np arr = np.arange(5) len_arr = len(arr) print("Array elements: ",arr) print("Length of NumPy array:",len_arr)

**Output:**

Array elements: [0 1 2 3 4] Length of NumPy array: 5
