How do you define a class in Python?

Defining a class in Python is accomplished using the class keyword followed by the class name, which is the correct approach. This structure indicates the beginning of a class definition. The syntax typically looks like this:

class ClassName:

class body (attributes and methods)

The use of the `class` keyword is essential as it tells Python to create a new class object, which can then be used to build objects (instances) that share the same structure and behaviors defined within the class.

In contrast, attempting to use keywords such as `define` or `function` does not correspond to class definitions in Python and would result in syntax errors. Additionally, creating an object directly does not establish a class; instead, it simply instantiates an object from an existing class. Understanding how to properly define a class is fundamental to utilizing object-oriented programming principles in Python.
