Exam Friday.
Sample Exam
Drop deadline Nov 2
Today: debugging, reviewing.
Most important skill - tracing the code, you pretending to be JES and running the code to see what is happening.
Still can't see what the problem is? Some other key techniques are...
Getting rid of everything (put # at the beginning of the line), and add things back in one or a few lines at a time, each time checking to make sure what you have so far works right. Eventually, you will see the problem happen again.
Using print to print things out, to make sure things are working the way you think they should be working.
Next time: Exam.
And make sure to take the quiz, and type things into JES to try them out!
