Dive into Queue Module in Python -It’s more than FIFO

Queue is a very practical data structure. It’s normally compared with stackarraylinked list, and other linear data structures. What makes a linear structure differs from another is where additions and removals occur.

Queue data structure has three types: FIFO, LIFO, and Priority Queue. The queue module in Python implements all of these types. Besides, it’s extremely useful in thread programming as well which makes this module even more shining.

In this article, I will first help you refresh knowledge on the data structures and learn how to use module queue. Then I will show you how to use queue to solve 2 different multi-threading problems. In the end, I will talk about the pros and cons of this module.

Data Structures

Before moving to some of the advanced features, let’s talk a bit about the queue data structure and learn how to use the module to create a “simple” queue.

FIFO — First in, First out

This is the basic type of queue. Elements inserted first will be removed first, which works like a waiting list in the real world. The earlier you are added to the list, the earlier you will get the concert ticket.

The Python module provides queue.Queue() and queue.SimpleQueue() that implements a FIFO queue. queue.SimpleQueue() is a new feature in Python 3.7. There are 2 differences between them:

  1. SimpleQueue() doesn’t do task tracking in the thread programming. Thread programming will be discussed later.
  2. SimpleQueue() is an unbounded FIFO queue while Queue() can have an upper bound. In both classes, if the queue is empty, get() operation will be blocked until new elements are inserted. In Queue(), if the queue is full, the put() operation will be blocked as well until elements are removed. This will never happen to SimpleQueue(). According to Python doc, it’s possible to disable the block using block=False in both get() and put(), then you will receive a queue.Full and queue.Empty exception immediately.

Top 20 Most Useful Python Modules or Packages

 March 25, 2021  Deepak@321  0 Comments

Welcome to my blog, In this article, we will learn the top 20 most useful python modules or packages and these modules every Python developer should know.

Hello everybody and welcome back so in this article I’m going to be sharing with you 20 Python modules you need to know. Now I’ve split these python modules into four different categories to make little bit easier for us and the categories are:

  1. Web Development
  2. Data Science
  3. Machine Learning
  4. AI and graphical user interfaces.

Near the end of the article, I also share my personal favorite Python module so make sure you stay tuned to see what that is also make sure to share with me in the comments down below your favorite Python module.

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map

Difference Between Python Module and Python Package?

Difference between python module and python package?

What’s the difference between a Python module and a Python package?

Module:  It is a simple Python file that contains collections of functions and global variables and has a “.py”  extension file. It’s an executable file and we have something called a “Package” in Python to organize all these modules.

Package:  It is a simple directory which has collections of modules, i.e., a package is a directory of Python modules containing an additional init.py  file. It is the init.py  which maintains the distinction between a package and a directory that contains a bunch of Python scripts. A Package simply is a namespace. A package can also contain sub-packages.

When we import a module or a package, Python creates a corresponding object which is always of type module . This means that the dissimilarity is just at the file system level between module and package.

How to Create a Queue in Python

Implement the queue data structure using Python

queue is a linear data structure that follows the First In First Out (FIFO) principle. That means the first element that is added to the queue is the first one to be removed. It has similarities to stack. Often queue and stack are studied together. But to keep things simple and short I decided to write two separate articles on them. Here is my article on how to create a stack in Python:

But in this article, we will learn how to create a queue. Let’s get started!
