It has two different parameters. This is useful when constructing programs that must accept multiple types of data without explicitly specifying the type. It is mainly used to identify data types at runtime and to build classes programmatically when needed. You can pass in either the variable referencing an object or the object itself. Major new features of the 3. For example, if the input is a string, you will get the output Since everything is an object in Python programming, Python data types are classes and variables are instances (objects) of these classes. Traditionally, types have been handled by the Python interpreter in a flexible but implicit way.
