How to Sort QListWidget Numeric Values Correctly | PyQt5 Tutorial

By default, when you sort a list in a QListWidget (in PyQt5, PySide2, Qt), the items are treated as regular text (or regular string). So when you are applying a sorting action to a list, the list will be sorted based on the string data type.

By default, when you sort a list in a QListWidget (in PyQt5, PySide2, Qt), the items are treated as regular text (or regular string). So when you are applying a sorting action to a list, the list will be sorted based on the string data type. This is an acceptable behavior if your items are text-based, but not when your list items are integers. In this PyQt5 tutorial, I will show you how to modify your PyQt5 code to properly sort numeric values.

PyQt is a library created by Riverbank based on the Qt framework to let you build desktop applications in Python. (An alternative is PySide2, by Qt the company itself).

Qt framework itself is written in C++, and the framework is also available in other programming languages, such as Java and C++. By using Python, we can build applications much more rapidly.

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

Today you're going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates. We gonna use Python OS remove( ) method to remove the duplicates on our drive. Well, that's simple you just call remove ( ) with a parameter of the name of the file you wanna remove done.

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc.. You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like __init__, __call__, __str__ etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).

The OS module is a python module that provides the interface for interacting with the underlying operating system that Python is running.
