The id() function in Python is used to get the unique identifier of an object. It returns an integer that represents the memory address of the object in the computer's memory.

        The purpose of the id() function is to uniquely identify an object during its lifetime. Each time an object is created, it is assigned a unique identifier that remains constant throughout its lifetime. The id() function can be useful for debugging purposes, as it allows you to check if two objects are the same or different.

        For example, consider the following code:

a = 10
b = 10
print(id(a))
print(id(b))

        In this code, the id() function is used to get the memory address of the integer objects a and b. Since integers are immutable in Python, the integer objects with the same value (in this case, 10) will have the same memory address. Therefore, the output of this code will be the same for both a and b, and will represent the memory address of the integer object with the value 10:
