Everything is an object

By

 Python treats every value or data item whether numeric, 

string, or other type (discussed in the next section) as 

an object in the sense that it can be assigned to some 

variable or can be passed to a function as an argument.

Every object in Python is assigned a unique identity 

(ID) which remains the same for the lifetime of that object. 

This ID is akin to the memory address of the object. The 

function id() returns the identity of an object.

How to add comments in python ?

For large and complex software, it may  require programmers to work in teams and sometimes,  a program written by one programmer is required to be  used or maintained by another programmer. In such  situations, documentations in the form of comments  are needed to understand the working of the program. Write a Python program to find the sum of  two numbers. #Program 5-4 #To find the sum of two numbers num1 = 10 num2 = 20 result = num1 + num2 print(result)  Output: 30
