In Python, methods are functions that are associated with an object and can manipulate the data contained within that object. They are essential for writing efficient and organized code, particularly in the context of Object-Oriented Programming (OOP). Methods allow developers to perform complex operations with minimal code, enhancing readability and maintainability.

There are different types of methods in Python, including instance methods, class methods, and static methods. Instance methods take self as the first parameter, allowing them to access instance-specific data. Class methods take cls as the first parameter and can modify class state that applies across all instances. Static methods do not take any special first parameter and behave like regular functions but belong to the class’s namespace.

Python also provides built-in methods that come pre-defined with the language, which can be used across various data types such as strings, lists, and dictionaries. For example, string methods like .upper() and list methods like .append() facilitate data manipulation efficiently ³⁴.
