Watch Now This tutorial has a related video course created by the Real Python team. Watch it together with the written tutorial to deepen your understanding: Defining and Calling Python Functions A Python function is a named block of code that performs specific tasks and can be reused in other parts of your code. Python has several built-in functions that are always available, and you can also create your own. These are known as user-defined functions. To define a function […]

Creating software is an achievement worth celebrating. But software is never static. Bugs need to be fixed, features need to be added, and security demands regular updates. In today’s landscape, with agile methodologies dominating, robust DevOps systems are crucial for managing an evolving codebase. That’s where GitHub Actions shine, empowering Python developers to automate workflows and ensure their projects adapt seamlessly to change. GitHub Actions for Python empowers developers to automate workflows efficiently. This enables teams to maintain software quality […]

In shell scripts, the shebang line (#!) specifies the path to the interpreter that should execute the file. You can place it at the top of your Python file to tell the shell how to run your script, allowing you to execute the script directly without typing python before the script name. The shebang is essential for Unix-like systems but ignored on Windows unless using specific compatibility layers. By the end of this video course, you’ll understand that: A shebang […]

You may have begun your Python journey interactively, exploring ideas within Jupyter Notebooks or through the Python REPL. While that’s great for quick experimentation and immediate feedback, you’ll likely find yourself saving code into .py files. However, as your codebase grows, your Python script structure efficiency becomes increasingly important. Transitioning from interactive environments to structured scripts helps promote readability, enabling better collaboration and more robust development practices. This tutorial transforms messy scripts into well-organized, shareable code. Along the way, you’ll […]
