* 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!
