Qt Designer and Python: Build Your GUI Applications Faster

To create a GUI for your windows and dialogs in PyQt, you can take two main paths: you can use Qt Designer, or you can hand code the GUI in plain Python code. The first path can dramatically improve your productivity, whereas the second path puts you in full control of your application’s code. GUI applications often consist of a main window and several dialogs. If you’re looking to create these graphical components in an efficient and user-friendly way, then […]

Python Inner Functions: What Are They Good For?

Inner functions, also known as nested functions, are functions that you define inside other functions. In Python, this kind of function has direct access to variables and names defined in the enclosing function. Inner functions have many uses, most notably as closure factories and decorator functions. In this tutorial, you’ll learn how to: Provide encapsulation and hide your functions from external access Write helper functions to facilitate code reuse Create closure factory functions that retain state between calls Code decorator […]

Python Modulo: Using the % Operator

Python supports a wide range of arithmetic operators that you can use when working with numbers in your code. One of these operators is the modulo operator (%), which returns the remainder of dividing two numbers. Modular operations are useful to check if a number is even or odd, simplifying cycling through data, and doing non-decimal based units conversion. In this course, you’ll learn: How modulo works in mathematics How to use the Python modulo operator with different numeric types […]

Python Microservices With gRPC

Microservices are a way to organize complex software systems. Instead of putting all your code into one app, you break your app into microservices that are deployed independently and communicate with each other. This tutorial teaches you how to get up and running with Python microservices using gRPC, one of the most popular frameworks. Implementing a microservices framework well is important. When you’re building a framework to support critical applications, you must ensure it’s robust and developer-friendly. In this tutorial, […]

Brython: Python in Your Browser

If you’re a web developer who prefers writing Python over JavaScript, then Brython, a Python implementation that runs in the browser, may be an appealing option. JavaScript is the de facto language of front-end web development. Sophisticated JavaScript engines are an inherent part of all modern Internet browsers and naturally drive developers to code front-end web applications in JavaScript. Brython offers the best of both worlds by making Python a first-class citizen language in the browser and by having access […]
