Outline for April 24, 2014

1. Finishing up calculating π using a Monte Carlo method
   1. Fifth step: plot the points [mc5.py]
   2. Sixth step: add the results to the plot [mc6.py]
2. How the for loop actually works
   1. For variable loops through the list
   2. Iterator: every time it is called, generates next item in the list
3. Scope: global, local, parameters [scope.py]
4. Handling exceptions
   1. except [except0.py]
   2. except error [except1.py]
   3. else [except2.py]
   4. except error as msgvar [except3.py]
   5. finally [except4.py]
   6. Exceptions in a function: who handles them? [except5.py, except6.py]
   7. Using global variables as error flags [except6a.py]
   8. raise [except7.py]
5. Common exceptions
   1. ZeroDivisionError — attempt to divide (or take the remainder of) something by 0
   2. TypeError — operation or function applied to operand of wrong type
   3. SyntaxError — Python parser encountered a malformed statement
   4. NameError — local or global name is not found
   5. ValueError — built-in function or operation applied to operator with illegal value
   6. EOFError — input function encounters an end of file
   7. Keyboard Interrupt — user hit the interrupt key (usually control-C)
