Python Array length

In Python, the length of an array can be obtained using the len() function. The len() function returns the number of elements in the array. In this article, we will see how we can find the length of Python Arrays.

Example:

arr = [1, 2, 3, 4, 5]
Length = 5

Python Array length

Python uses Lists instead of arrays. Both are similar and are used to work as an array. Let us see how we can find the length of a Python array.

Python Array Length using len() Method

The Python len() function can be used to find the length of an array in Python. The len() function returns the length of the list or array.

Output:

5

Python Array Length using Array Module

Here we are going to use the Python array module for creating the array, and then len() function is used to obtain the length of the array.

Output:

3

Python Array Length using Numpy Module

We can also use Python Numpy module to create an array and then use the len() function to calculate the length of the array.

Output:

3

What is the Difference Between a Python Array and a List?

The main differences between a Python array and a list are as follows:
