* Outline

  - Showing output to the user.

  - Taking input from the user. 

* Question 1

  What happens when you do ~print "x is %d y is %f" %(x, y)~

* Solution 1

  ~int~ value of ~x~ and ~float~ value of ~y~ are printed corresponding to the

  modifiers used in the ~print~ statement

* Question 2

  Enter the number 5.6 as input and store it in a variable called

  ~c~. 

* Solution 2

  #+begin_src python

    In []: c = raw_input() 

    5.6

    In []: c

  #+end_src

* Question 3

  What happens when you do not enter anything and hit enter

* Solution 3

  #+begin_src python

    In []: c = raw_input() 

    <RET>

    In []: c

  #+end_src

* Question 4

  How do you display a prompt and let the user enter input in a new line

* Solution 4

  #+begin_src python

    In []: ip = raw_input("Please enter a number in the next line\n> ")

  #+end_src

* Summary

  You should now be able to --

   + Print a value "as is" 

   + Print a value using using modifiers

   + Accept input from user

   + Display a prompt before accepting input

* Thank you!
