Python is a dynamically typed language, meaning variables do not require explicit type declarations; instead, objects carry type information at runtime. To inspect the type of an object, Python provides the built-in function type(). When you pass a variable or value into type(), it returns the object’s class, which represents its data type. For example, type(5) returns , type(3.14) returns , and type("hello") returns . This is commonly used in debugging, learning exercises, and when writing functions that must behave differently depending on input types.

Textbook discussions often pair type() with Python’s object model: everything in Python is an object, and each object is an instance of some class. type() reveals that class. In addition, type() can be used in more advanced ways, such as dynamic class creation, but its foundational educational use is type inspection.

The other options are not correct because GetVar(), Show(), and Data() are not standard Python built-ins for type checking. While developers can define functions with those names, they are not part of Python’s core language or standard library in the sense required by the question. For typical coursework and professional Python usage, the correct and universally accepted function is type().
