Announcements:

• The deadline for lab5 is the end of Sunday, April 1.

• Lab 5 note:

  Don't write

          else:
              y = y
  

  This is pointless and just confuses anyone reading the program. I think that people who write that might be forgetting that the 'else' is optional. You can omit both the "else:" and any statements within the else. "If you have nothing to say, don't say it."

• Alert: My "fatpixel" package seems not to work when run under Wing-101. I'm not sure why, and I won't be able to fix it prior to the lab time.
  Unfortunately you'll have to run it from a terminal window, just like you'd have to do if you were using nedit instead of wing-101. You can still use wing-101 to edit; just save and switch to a terminal window.
  Sorry about this.
