Python is a versatile programming language, widely used for developing web applications, scientific computing, data analysis, and artificial intelligence. Overriding method names in Python is a common challenge for many programmers. Fortunately, there is a solution: double-underscores.

The Basics of Double-Underscores

Double-underscores are used to create special class attributes or methods in Python, such as dunder methods. Dunder stands for double underscore, thus the name. These methods and attributes have special behavior that can be useful for overriding regular method names.

What are Dunder Methods?

Dunder methods are special methods in Python, starting and ending with double underscores. Some examples include __init__(), __str__(), __len__(), and __add__(). They are invoked automatically by the interpreter when certain events occur, such as creating an instance of a class or using the + operation on objects.

Why Use Dunder Methods?

Dunder methods provide a way to customize the behavior of classes and objects in Python. For example, by defining the __str__() method, you can specify how instances of your class are printed when using the print() function. By using dunder methods, you can override the default behavior of regular method names.

Advanced Tips and Tricks

While using dunder methods is essential for overriding method names in Python, there are advanced tips and tricks to master.

Use the __call__() Method

The __call__() method allows you to define a class as callable functions in Python. Doing so makes it easier to use instances of the class as functions.

Use the __getattr__() Method

The __getattr__() method is used to retrieve an attribute of a class that doesn’t exist. By using this method, you can customize the behavior when an attribute is called that doesn’t exist.

Use the __setitem__() Method

The __setitem__() method is used to assign a value to an item in a dictionary. By using this method, you can customize the behavior of dictionaries when you want to set an item in them.

Comprehensive Guide to Overriding Method Names with Double-Underscores

If you’re struggling to override method names in Python, then look no further. This article provides a comprehensive guide to using double-underscores to solve this problem.

Step-by-Step Process

The step-by-step process involves understanding how dunder methods work and how to use them to override standard method names. By following the steps outlined in this article, you’ll be able to quickly and easily override method names in your Python programs.

Comparison Table

Regular Method Name Dunder Method Name Description
add(x, y) __add__(self, other) Returns the sum of two objects
len(x) __len__(self) Returns the length of an object
pop(key, default=None) __getitem__(self, key) Returns the value of an item in a dictionary


Overriding method names in Python can be challenging, but using double-underscores provides a simple and effective solution. By mastering dunder methods and following the step-by-step process outlined in this guide, you’ll be able to override method names with ease. Keep exploring and experimenting with Python’s capabilities to become an expert in this rewarding field.

When it comes to Python, there are numerous tips and tricks that developers can use to enhance their coding skills. One such tip is overriding method names with double-underscores. Here are some common questions people ask about this topic:

1. What does it mean to override a method name with double-underscores in Python?

  • Overriding a method name with double-underscores in Python means that you are specifying a custom behavior for a built-in method.
  • For example, if you override the __add__() method, you can define how two objects of your class should be added together.

2. Why would I want to override a method name with double-underscores?

  • By overriding a method name with double-underscores, you can customize the behavior of your class to fit your needs.
  • This can be particularly useful if you are working with built-in methods and want to modify their behavior without having to rewrite them from scratch.

3. What other method names can I override with double-underscores?

  • In addition to __add__(), you can also override other built-in methods such as __init__(), __str__(), and __repr__().
  • Each method has its own specific purpose and can be used to customize different aspects of your class’s behavior.

4. Are there any best practices for overriding method names with double-underscores?

  • It’s generally recommended to only override built-in methods when it makes sense for your class’s specific use case.
  • You should also be careful not to accidentally override methods that are used by other parts of your code or by Python itself.

5. Can I override method names with single underscores?

  • No, method names with a single underscore have a specific meaning in Python and are typically used to indicate that a method or variable is intended for internal use only.
  • Overriding these methods can lead to unexpected behavior and should generally be avoided.

By understanding how to override method names with double-underscores in Python, you can take your coding skills to the next level and create more powerful, customizable classes.
