Until now, you’ve focused on how to use the continue statement effectively in your code. But have you ever wondered what Python actually does when it encounters continue inside a loop? This section pulls back the curtain to explore how Python parses and executes your code, helping you understand what’s really going on when your loops skip ahead. Understanding the Official Documentation As you learned earlier, continue only works inside a loop—it has no function outside a loop and will […]

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: Hands-On Python 3 Concurrency With the asyncio Module Python’s asyncio library enables you to write concurrent code using the async and await keywords. The core building blocks of async I/O in Python are awaitable objects—most often coroutines—that an event loop schedules and executes asynchronously. This programming model lets you efficiently manage multiple I/O-bound tasks […]

Python has a complete set of built-in exceptions that provide a quick and efficient way to handle errors and exceptional situations in your code. Knowing the most commonly used built-in exceptions is key for you as a Python developer. This knowledge will help you debug code because each exception has a specific meaning that can shed light on your debugging process. You’ll also be able to handle and raise most of the built-in exceptions in your Python code, which is […]
