I've just shipped a new tool, the Interactive Return Explorer for Python Functions. This is a runnable script designed to help visualize function returns.
At its core, it's a Python decorator. You can apply this decorator to any function in your Python code. When that decorated function is called, the explorer will print its return value directly to the console. If a function doesn't explicitly return a value, it will display None, making that behavior explicit.
The primary audience for this tool is Python beginners. Understanding how return statements work and how values are passed out of functions can be a common hurdle. By providing immediate feedback on what a function returns each time it's executed, the Interactive Return Explorer aims to make this concept more concrete and easier to grasp. It allows users to observe the flow of data out of functions in real-time without needing to add print statements manually throughout their code.
