Book Management System with Python & SQLite3

In this article I will cover how to build a SQL (Structured Query Language) based book management system in Python with an integrated graphical user interface.

A few python libraries you will need to import for this program:

  • numpy
  • sqlite3
  • json
  • easygui
  • platform
  • fuzzywuzzy
  • glob

Now before I go any further let me give you a short introduction. You might be wondering…why easygui? Why not rather Tkinter or PyQt to craft the GUI? Well… about a year ago I could not print “hello world” in a python IDE, neither did I have a clue what an IDE is. Around the end of 2019 with no domain knowledge whatsoever I hopped on a Data Science boot camp and started to familiarize myself with the python programming language so I am very much inexperienced still.

When you build a program which is designed for an end-user, normally they would prefer not to operate it via a cli (command line) environment. Users want to press buttons that look nice and the program must preferably be intuitive and easy to navigate.

Due to my limited experience I stumbled upon the easygui library and I found that its quite easy to use. This will likely be one of my last posts on using easygui as I don’t want to stagnate on this library but I want to show people who have little experience how easy it is to build a GUI around a program with easygui. Without further ado lets begin:

The data we are going to use for this program is a .json file I compiled myself. Its quite sparse but it will do the job. Feel free to compile your own and use that if you wish, just make sure you keep the format the same. You can name it whatever you like. Take care to save the .py and .json file in the same location. Below is a quick view of the books.json file:

books.json

The JSON keys are intended to be self-explanatory but lets quickly go through them:

id: book id (this can also be changed to ISBN for example)

Title: book title

Author: book author

Qty: book quantity

Right, now lets fire up the IDE and start by importing the above mentioned python libraries:

The program consist out of 27 functions. When you run the program, only one function named ‘which_way()’ gets called. From there on depending on user input, alternate functions gets called from within other functions. I will not cover every single one of them here as a few share similarity however I will include them all in the source code.

Lets have a look at the first one:

Image for post

This function spawns the main menu of the book manager. As this program consist of functions only we declare some variables as global in order for them to be available when referred to from other functions.

For the sake of simplicity whilst testing the GUI, I set the login to ‘admin’ and password as ‘1234’ as seen above on lines 26/27. You change this as you wish. After saving login, password and initializing the ‘boolean’ variable as ‘True’ we define the easygui choicebox parameters which sets the display text and options.

User input(text(string) or choice the user clicks on) gets saved in the ‘fieldValues’ variable. If the user chooses to create a new database from a .json file upload, the boolean variable gets set to ‘False’ and login_window(boolean) function gets called.

Alternatively if the user chooses to continue where they left off from a previous session, they can load the existing _db file by choosing the ‘Continue on existing database’ option which will call on the login_window(boolean) function with the boolean variable set to True. If however the user presses cancel, the program terminates.

Why use Python for Software Development

No programming language is pretty much as diverse as Python. It enables building cutting edge applications effortlessly. Developers are as yet investigating the full capability of end-to-end Python development services in various areas. 

By areas, we mean FinTech, HealthTech, InsureTech, Cybersecurity, and that's just the beginning. These are New Economy areas, and Python has the ability to serve every one of them. The vast majority of them require massive computational abilities. Python's code is dynamic and powerful - equipped for taking care of the heavy traffic and substantial algorithmic capacities. 

Programming advancement is multidimensional today. Endeavor programming requires an intelligent application with AI and ML capacities. Shopper based applications require information examination to convey a superior client experience. Netflix, Trello, and Amazon are genuine instances of such applications. Python assists with building them effortlessly. 

5 Reasons to Utilize Python for Programming Web Apps 

Python can do such numerous things that developers can't discover enough reasons to admire it. Python application development isn't restricted to web and enterprise applications. It is exceptionally adaptable and superb for a wide range of uses.

Robust frameworks 

Python is known for its tools and frameworks. There's a structure for everything. Django is helpful for building web applications, venture applications, logical applications, and mathematical processing. Flask is another web improvement framework with no conditions. 

Web2Py, CherryPy, and Falcon offer incredible capabilities to customize Python development services. A large portion of them are open-source frameworks that allow quick turn of events. 

Simple to read and compose 

Python has an improved sentence structure - one that is like the English language. New engineers for Python can undoubtedly understand where they stand in the development process. The simplicity of composing allows quick application building. 

The motivation behind building Python, as said by its maker Guido Van Rossum, was to empower even beginner engineers to comprehend the programming language. The simple coding likewise permits developers to roll out speedy improvements without getting confused by pointless subtleties. 

Utilized by the best 

Alright - Python isn't simply one more programming language. It should have something, which is the reason the business giants use it. Furthermore, that too for different purposes. Developers at Google use Python to assemble framework organization systems, parallel information pusher, code audit, testing and QA, and substantially more. Netflix utilizes Python web development services for its recommendation algorithm and media player. 

Massive community support 

Python has a steadily developing community that offers enormous help. From amateurs to specialists, there's everybody. There are a lot of instructional exercises, documentation, and guides accessible for Python web development solutions. 

Today, numerous universities start with Python, adding to the quantity of individuals in the community. Frequently, Python designers team up on various tasks and help each other with algorithmic, utilitarian, and application critical thinking. 

Progressive applications 

Python is the greatest supporter of data science, Machine Learning, and Artificial Intelligence at any enterprise software development company. Its utilization cases in cutting edge applications are the most compelling motivation for its prosperity. Python is the second most well known tool after R for data analytics.

The simplicity of getting sorted out, overseeing, and visualizing information through unique libraries makes it ideal for data based applications. TensorFlow for neural networks and OpenCV for computer vision are two of Python's most well known use cases for Machine learning applications.

Summary

Thinking about the advances in programming and innovation, Python is a YES for an assorted scope of utilizations. Game development, web application development services, GUI advancement, ML and AI improvement, Enterprise and customer applications - every one of them uses Python to its full potential. 

The disadvantages of Python web improvement arrangements are regularly disregarded by developers and organizations because of the advantages it gives. They focus on quality over speed and performance over blunders. That is the reason it's a good idea to utilize Python for building the applications of the future.
