Python has the following data types built-in by default, in these categories: type() function can be used at that point to determine the type of text extracted and then change it to other forms of string before we use string functions or any other operations on it. type() with three arguments can be used to dynamically initialize classes or existing classes with attributes. In this tutorial, we will learn about the Python type() function with the help fo examples. The type() function either returns the type of the object or returns a new type object based on the arguments passed.
