In Python, the size of an array might be obtained utilizing the len() operate. The len() operate returns the variety of components within the array. On this article, we are going to see how we are able to discover the size of Python Arrays.
Instance:
arr = [1, 2, 3, 4, 5]
Size = 5
Python Array size
Python makes use of Lists as an alternative of arrays. Each are related and are used to work as an array. Allow us to see how we are able to discover the size of a Python array.
Python Array Size utilizing len() Methodology
The Python len() operate can be utilized to seek out the size of an array in Python. The len() operate returns the size of the checklist or array.

Python Array Size utilizing Array Module
Right here we’re going to use the Python array module for creating the array, after which len() operate is used to acquire the size of the array.

Python Array Size utilizing Numpy Module
We will additionally use Python Numpy module to create an array after which use the len() operate to calculate the size of the array.

What’s the Distinction Between a Python Array and a Listing?
The principle variations between a Python array and an inventory are as follows:
|
Python arrays are homogeneous, that means they will solely retailer components of the identical knowledge kind |
Python lists can retailer components of various knowledge sorts. |
|
Python arrays are usually extra memory-efficient than lists. They’re applied as a contiguous block of reminiscence |
Python lists are applied as dynamic arrays with further options, comparable to resizing and insertions/deletions. |
|
Python arrays supply fundamental operations comparable to indexing, slicing, appending, and ingredient project. |
Python lists, being extra versatile, assist a wider vary of operations, together with insertions, deletions, sorting, reversing, and extra. |
|
Arrays can present higher efficiency because of their reminiscence effectivity and the flexibility to leverage sure mathematical libraries within the case of a big assortment of homogeneous components for numerical computations. |
Lists, being extra versatile, might have barely decrease efficiency in such situations |
