Tuesday - Wednesday (12/14/10 - 12/15/10)
Agenda:
- Demo Looping with GASP Exercises
- Read and walk through Case Study: Catch
Friday - Monday (12/10/10 - 12/13/10)
Warmup:
- Copy and paste the following code
from gasp import * # import everything from the gasp library
begin_graphics() # open the graphics canvas
Box((20, 20), 100, 100) # the house
Box((55, 20), 30, 50) # the door
Box((40, 80), 20, 20) # the left window
Box((80, 80), 20, 20) # the right window
Line((20, 120), (70, 160)) # the left roof
Line((70, 160), (120, 120)) # the right roof
update_when('key_pressed') # keep the canvas open until a key is pressed
end_graphics() # close the canvas (which would happen
# anyway, since the script ends here, but it
# is better to be explicit).
- Try changing some of the numbers in the above Box() and Line() functions...what happens? What do you think each of those numbers/arguments corresponds to?

Tuesday (12/7/10)
Warmup:
- Write a loop that runs 30 times (using x as a counter variable)
- Inside the loop, print x*" ","*"
- Don't forget to increment your counter variable
- Write another loop that runs from 30 down to 0
- Inside the loop, print x*" ","*"
- Don't forget to decrement your counter variable

Monday (12/6/10)
Warmup:
- Initialize a counter variable i to 1
- Create another variable old_i that starts at 1 also
- Create a loop that runs up to 1000
- print out i and old_i on the same line (use a comma)
- save i into old_i
- increment i
- What happens when you execute the above code?
