* Objectives
At the end of this tutorial,you will be able to, 

 - Print some value.
 - Print using modifiers.
 - Take input from user.
 - Display a prompt to the user before taking the input.
   
* Exercise 1
 - What happens when you do
   print "x is %d, y is %f" %(x, y)
* Exercise 2
 - Enter the number 5.6 as input and store it in a variable called
  ~c~. 
* Exercise 3
 - What happens when you do not enter anything and hit enter
* Exercise 4
  - How do you display a prompt and let the user enter input in a new line
* Summary
 In this tutorial, we have learnt to,

 - Use the print statement.
 - Use the modifiers %d, %f, %s in the print statement.
 - Take input from user by using ``raw\_input()''. 
 - Display a prompt to the user before taking the input by passing 
    a string as an argument to ``raw\_input''.
* Evaluation
1. ``a = raw\_input()'' and user enters ``2.5''.
   What is the type of a?

    - str
    - int
    - float
    - char

2. ``a = 2'' and ``b = 4.5''. 
   What does print "a is %d and b is %2.1f" %(b, a) print?

   - a is 2 and b is 4.5
   - a is 4 and b is 2
   - a is 4 and b is 2.0
   - a is 4.5 and b is 2

* Solutions
1. str

2. a is 4 and b is 2.0
