![]() ![]() ![]() PRICE - This will be an integer value and will hold the price of our book.you cannot create a row with an empty name value. NAME - This is where the name of our book will go, It has a type TEXT, and NOT NULL, that this column is not nullable, i.e.Lastly AUTOINCREMENT - this tells sqlite3 to auto-populate that value with a unique key. a unique identifier for whatever created row in the table. ID - which has the type INTEGER, and we made it a PRIMARY KEY i.e.Inside the bracket, we have the columns, which are:.CREATE TABLE BOOKS - very readable, this creates a table, if not exists- we added this statement, because every time our app runs, we will be calling the create table function, and we will get an error otherwise, saying stuff like the table already exists.Now, to the query part, this is where things get interesting if you've never read or coded any SQL before.The file will be automatically created, if it does not exist. db = nnect('database.db') - This is very straightforward, For us to perform any action in our database, we have to connect with it.import sqlite3 Create a Table with SQLite # db.pyĬREATED_AT DATETIME default current_timestamp, Note: SQLite comes with Python by default pip install is unnecessary. Here are a list of what needs to be done: We will first tackle our db functions and then fully concentrate on the UI. main.py this is where the UI stuff with pyqt5 will be.db.py this is where all our database functions will reside.Our project will have a very basic structure, which looks like something below: I will give a detailed explanation of what we're doing as we implement them. We will be using SQLite3 for the database, a very lightweight implementation of SQL you've probably heard of it or used it. Like any other full-stack project you will be building in the future or have built before, you always need a database of some sort, and that is not less for our app either. In this article, we will build a book repo it is a very basic but nerdy idea, i.e., an app we can use to record books we've read. Apart from being customizable with CSS2, Another added beauty of PyQT is that it can build UI to adapt to the native implementation, i.e., your app blends in and looks just the way other apps in whatever operating system your user use looks like. ![]() This is where PyQT5 comes in It is a framework built on QT, which is a C++ framework for building UI. Users might want something functional, but they also love a good UI. Most beginners are more familiar with Tkinter, which is by far the easiest way to build GUI for whatever side project you're building quickly.īut Tkinter is less customizable, and the UI looks terrible if you don't use ttkboostrap. PyQt5 is a Python framework for building GUI applications. Step up your coding game with AI-powered Code Explainer. ![]()
