1 -   The first program in any programming language is always the "HELLO WORLD". So lets begin with this simple code :- 

---------------------------------------------------------------------------------

print ("HELLO WORLD")

---------------------------------------------------------------------------------

Thats it!!!

Now the function "print" is new here . Its function is to print something on the console. 

("HELLO WORLD")

As we know HELLO WORLD is a string hence we have to put it inside two quotes " ".

2 - A program that adds two number(according to the user)  :-

--------------------------------------------------------------------------------------------------------------------------

num1 = int(input("ENTER YOUR FIRST NUMBER"))

num2 = int(input("ENTER YOUR SECOND NUMBER"))

print (num1+num2)

--------------------------------------------------------------------------------------------------------------------------

Here a new function has been introduced INPUT. What it does is that it asks the user to enter their number and then it stores that number into the variable name "num1" or "num2". So whenever the variables are called , the input enterd by the user is taken and added.  Hence, we use input whenever we need to take the data enterd by the user.

Next , inside the print function, we just add the two variables by putting  a "+" sign between them.
