• The third parse example has a stray quote. It should be parse("(define square (lambda (x) (* x x)))")
• One of the examples for question 3 was incorrect on the problem set handout. The third example should be (cdr (cons 1 2)) evaluates to 2.
• For question 4, note that names in Python cannot include question marks, so you will have to use a different name for the Python procedure you use to implement null?.
• To run Python in the ITC labs:
  1. From the Start menu, select "SEAS -> Python 2.4 -> IDLE (Python GUI)"
  2. Be patient (it takes about 10 seconds to start up)
  3. Inside the Python shell, select "File -> Open" and select the charme.py file.
  To run the Python module, select "Run -> Run Module" (or F5) in the editor window. This will return the focus to the Python shell with your module loaded.
• Be careful not to reload the module while the evalLoop() is still running in the shell. If you try and load the charme.py file while the evalLoop() is running in the shell, it will send the shell into an infinite loop, where it will no longer respond to charme or python statements (and you will need to restart the shell which takes a while). The only way to get out of this is to restart the shell. To avoid this, remember to type "quit" in the evalLoop before trying to reload the charme.py file.
