Interactive Quiz ⋅ 10 QuestionsBy Martin Breuss Share In this quiz, you’ll test your understanding of Python’s continue statement. The continue statement allows you to skip code in a loop for the current iteration, jumping immediately to the next iteration. It’s used exclusively in for and while loops, allowing you to control the flow of execution, bypass specific conditions, and continue processing in a structured and predictable manner. The quiz contains 10 questions and there is no time limit. You’ll […]

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 […]

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: Binary, Bytes, and Bitwise Operators in Python Computers store all kinds of information as a stream of binary digits called bits. Whether you’re working with text, images, or videos, they all boil down to ones and zeros. Python’s bitwise operators let you manipulate those individual bits of data at the most granular level. You […]

In Python, a closure is typically a function defined inside another function. This inner function grabs the objects defined in its enclosing scope and associates them with the inner function object itself. The resulting combination is called a closure. Closures are a common feature in functional programming languages. In Python, closures can be pretty useful because they allow you to create function-based decorators, which are powerful tools. In this video course, you’ll: Learn what closures are and how they work […]
