+* 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!
