Python Built-In Function

id() function returns an integer, that is an unique identifier for the object. The id will be unique, and stays the same for the object lifetime.

print function is used to print/output text on the screen or to a file. print() is a built-in function in Python. Generally, we just pass a string as the first parameter, and the string literal is printed. We can use single or double quotes to enclose the string literals, as both are allowed to represent strings in Python.
