−* 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!
