Lecture 13:- Type() in Python

In Python, type() is a built-in function that is used to determine the data type of a given object. The type() function returns a type object, which represents the data type of the object. It is particularly useful when you want to check the data type of a variable or value during runtime.

The syntax of the type() function is as follows:

pythonCopy code

type(object)

Here, object is the object whose data type you want to determine.

Example:

pythonCopy code

x = 42 y = "Hello" z = [1, 2, 3] print(type(x))  # Output: <class 'int'> print(type(y))  # Output: <class 'str'> print(type(z))  # Output: <class 'list'>

In this example, type(x) returns <class 'int'>, indicating that the variable x is of the integer data type. Similarly, type(y) returns <class 'str'>, indicating that y is of the string data type, and type(z) returns <class 'list'>, indicating that z is of the list data type.

The type() function is helpful when you want to perform different actions or logic based on the data type of a variable or object. For example, you might want to handle integers differently from strings or lists in your program.

Keep in mind that the type() function should be used primarily for debugging, introspection, or conditional checks. For general equality comparisons between objects, it is better to use the isinstance() function or direct comparison with specific data types using the == operator.
