Watch it together with the written tutorial to deepen your understanding: Starting With Python IDLE Python IDLE is the default integrated development environment (IDE) that comes bundled with every Python installation, helping you to start coding right out of the box. In this tutorial, you’ll explore how to interact with Python directly in IDLE, edit and execute Python files, and even customize the environment to […]

MySQL is one of the most popular database management systems (DBMSs) on the market today. It ranked second only to the Oracle DBMS in this year’s DB-Engines Ranking. As most software applications need to interact with data in some form, programming languages like Python provide tools for storing and accessing these data sources. Using the techniques discussed in this video course, you’ll be able to efficiently integrate a MySQL database with a Python application. You’ll develop a small MySQL database […]

Interactive Quiz ⋅ 12 QuestionsBy Bartosz Zaczyński Share In this quiz, you’ll test your understanding of Shallow vs Deep Copying of Python Objects. By working through this quiz, you’ll revisit the concepts of shallow and deep copying, and how they affect mutable objects in Python. The quiz contains 12 questions and there is no time limit. You’ll get 1 point for each correct answer. At the end of the quiz, you’ll receive a total score. The maximum score is 100%. […]

Python’s assignment statements don’t copy objects as they do in some other programming languages. Instead, they create bindings between your variable names and objects. For immutable objects, this distinction usually doesn’t matter. However, when you work with mutable objects or containers of mutable items, you may need to create explicit copies or “clones” of these objects. Explore the nuances of copying objects in Python and learn how to apply these techniques to manage mutable data structures effectively. Getting the Big […]

Interactive Quiz ⋅ 5 QuestionsBy Philipp Acsany Share In this quiz, you’ll test your understanding of the Python break statement. This keyword allows you to exit a loop prematurely, transferring control to the code that follows the loop. The quiz contains 5 questions and there is no time limit. You’ll get 1 point for each correct answer. At the end of the quiz, you’ll receive a total score. The maximum score is 100%. Good luck! Related Resources

In Python, the break statement lets you exit a loop prematurely, transferring control to the code that follows the loop. This tutorial guides you through using break in both for and while loops. You’ll also briefly explore the continue keyword, which complements break by skipping the current loop iteration. By the end of this tutorial, you’ll understand that: A break in Python is a keyword that lets you exit a loop immediately, stopping further iterations. Using break outside of loops […]

In this video course, you’ll learn how to create a Python dice roll simulator. The course guides you through building a text-based user interface (TUI) application that simulates rolling dice using Python’s random module. You’ll learn to gather and validate user input, use random.randint() for dice rolling, and display results with ASCII art. By the end of this video course, you’ll understand that: To simulate dice-rolling events, you can use random.randint() . To get the user’s input, you use the […]

Interactive Quiz ⋅ 11 QuestionsBy Martin Breuss Share In this quiz, you’ll test your understanding of Namespaces in Python. You’ll revisit how Python organizes symbolic names and objects in namespaces, when Python creates a new namespace, how namespaces are implemented, and how variable scope determines symbolic name visibility. The quiz contains 11 questions and there is no time limit. You’ll get 1 point for each correct answer. At the end of the quiz, you’ll receive a total score. The maximum […]

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: Navigating Namespaces and Scope in Python A Python namespace is a mapping from names to objects. It works like a dictionary where keys are object names and values are the objects themselves. Namespaces organize variables and functions in a dedicated space, allowing you to use multiple instances of the same name without conflict, as […]

Python’s .__dict__ is a special attribute in classes and instances that acts as a namespace, mapping attribute names to their corresponding values. You can use .__dict__ to inspect, modify, add, or delete attributes dynamically, which makes it a versatile tool for metaprogramming and debugging. In this tutorial, you’ll learn about using .__dict__ in various contexts, including classes, instances, and functions. You’ll also explore its role in inheritance with practical examples and comparisons to other tools for manipulating attributes. By the […]
