Basic Data Structure in Python

Python is a popular programming language known for its simplicity, versatility, and ease of use. One of the most important aspects of programming in Python is the effective use of data structures. Data structures in Python are a way of organizing and storing data in a specific format that can be easily accessed and manipulated by the programmer. In this blog, we will explore the most commonly used data structures in Python.

Lists Lists are one of the most commonly used data structures in Python. They are a collection of items that are ordered and mutable. Lists can contain items of different data types, including other lists. Lists are created using square brackets and individual items are separated by commas. Here is an example of creating a list:


my_list = [1, 2, 3, 'hello', 'world']

Tuples Tuples are similar to lists, but they are immutable. This means that once a tuple is created, it cannot be modified. Tuples are created using parentheses and individual items are separated by commas. Here is an example of creating a tuple:


my_tuple = (1, 2, 3, 'hello', 'world')

Dictionaries Dictionaries are a collection of key-value pairs that are unordered and mutable. They are created using curly braces and each key-value pair is separated by a colon. Here is an example of creating a dictionary:


my_dict = {'name': 'John', 'age': 30, 'city': 'New York'}

Sets Sets are a collection of unique items that are unordered and mutable. They are created using curly braces and individual items are separated by commas. Here is an example of creating a set:


my_set = {1, 2, 3, 4, 5}

Arrays Arrays are used to store a collection of elements of the same data type. They are more efficient than lists when working with large amounts of data. Arrays in Python are provided by the array module. Here is an example of creating an array:


import array as arr
my_array = arr.array('i', [1, 2, 3, 4, 5])

In conclusion, data structures play a crucial role in Python programming. They allow for efficient storage, retrieval, and manipulation of data. Understanding the different types of data structures in Python is essential for writing effective code. The data structures we discussed in this blog are just a few examples of what is available in Python, and there are many more to explore.

SSO — WSO2 API Manager and Keycloak Identity Manager

Image
In this article, we are going to see how to implement Single Sign-On (SSO) for WSO2 API Manager using Keycloak as a Federated Identity Provider. Also, we'll choose a deep-dive showing how debugging works with the WSO2 API Manager code to see what happens inside when it's configured with a third-party identity provider (i.e Keycloak in this example). High-Level Architecture This is what we are going to do in this tutorial. High-level architecture Software Needed Following softwares will be needed: WSO2 API Manager (2.6.0) Keycloak (6.0.1) Note : We aren’t getting to use WSO2 Identity Server as a middleman for this tutorial. The article is predicated on pure WSO2 API Manager 2.6.0 (all in one). Before We Start The tutorial will be divided into two parts. In the first part, I will explain how to install and configure Keycloak. In the second part, we will see how to install and configure the WSO2 API Manager. Before we start, let's modify the  /etc/hosts  file ...

Garbage Collectors - Serial vs. Parallel vs. CMS vs. G1 (and what’s new in Java 8)

The 4 Java Garbage Collectors – How the Wrong Choice Dramatically Impacts Performance When Garbage collection is one of those things that are generally known to impact performance, but beyond that – in terms of how it actually works – it’s pretty much a mystery to most of us. So, I thought I’d take a whack at covering the basics of GC, especially since this is an area that has seen some major changes and improvements with Java 8, especially with the removal of the PermGen and some new and exciting optimizations (more on this towards the end). When we speak about garbage collection, the vast majority of us know the concept and employ it in our everyday programming. Even so, there’s much about it we don’t understand, and that’s when things get painful. One of the biggest misconceptions about the JVM is that it has one garbage collector, where in fact it provides  four different ones , each with its own unique advantages and disadvantages. The choice of which one to use isn’t automati...

Recommendation System Using Word2Vec with Python

Image
Overview Recommendation engines are ubiquitous nowadays and data scientists are expected to know how to build one Word2vec is an ultra-popular word embeddings used for performing a variety of  NLP  tasks We will use word2vec to build our own recommendation system. Curious how NLP and recommendation engines combine? Let’s find out!   Introduction Be honest – how many times have you used the ‘Recommended for you’ section on Amazon? Ever since I found out a few years back that machine learning powers this section – I have been hooked. I keep an eye on that section each time I log into Amazon. There’s a reason companies like Netflix, Google, Amazon, Flipkart, etc. spend millions perfecting their recommendation engine. It is a powerful acquisition channel and enhances the customer’s experience. Let me use a recent example to showcase their power. I went to a popular online marketplace looking for a recliner. There were hundreds of them. From Traditional two-position recliners ...
