+* Outline
+  - Loop while a condition is true. 
+  - Iterate over a sequence
+  - Breaking out of loops.
+  - Skipping iterations.
+* Question 1
+  Write a ~while~ loop to print the squares of all the even
+  numbers below 10. 
+* Solution 1
+  #+begin_src python
+    In []: i = 2
+    
+    In []:  while i<10:
+     ....:     print i*i
+     ....:     i += 2
+  #+end_src
+* Question 2
+  Write a ~for~ loop to print the squares of all the even numbers
+  below 10.
+* Solution 2
+  #+begin_src python    
+    In []: for n in range(2, 10, 2):
+     ....:     print n*n
+  #+end_src
+* Question 3
+  Using the ~continue~ keyword modify the ~for~ loop to print the
+  squares of even numbers below 10, to print the squares of only
+  multiples of 4. (Do not modify the range function call.)
+* Solution 3
+  #+begin_src python    
+    for n in range(2, 10, 2):
+        if n%4:
+            continue      
+        print n*n
+  #+end_src
+* Summary
+  You should now be able to --
+  - use the ~for~ loop 
+  - use the ~while~ loop
+  - Use ~break~, ~continue~ and ~pass~ statements 
+* Thank you!
