Python id() Function
The id() function in Python returns a unique id of any specified object. For example:
a = [12, 42, 5, 5] b = (1, 43, 5) c = "Python Programming" print(id(a)) print(id(b)) print(id(c))
The snapshot given below shows the sample output produced by above Python program, demonstrating the id() function:
Note: Every object in Python gets assigned its own unique id, when it is created. Therefore you'll get different id for the same object, each time when you run the program.
Python id() Function Syntax
The syntax of id() function in Python, is:
id(obj)
where obj refers to an object such as list, string, tuple, class etc.
Python id() Function Example
Here is an example of id() function in Python.
num = 100 a = 100 print(id(100)) print(id(num)) print(id(a))
All the three print() statement prints the same output, that looks like:
2245638378960 2245638378960 2245638378960
This is because, id of a particular one remains constant during the lifetime of a program.
