Computer Science

Friday (12/10/10)

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).

• Recomment each line of code with Box() and Line()...what are the arguments into those functions?

Tuesday (12/7/10)

Warmup:

1. Write a loop that runs 30 times (using x as a counter variable)
   1. Inside the loop, print x*" ","*"
   2. Don't forget to increment your counter variable
2. Write another loop that runs from 30 down to 0
   1. Inside the loop, print x*" ","*"
   2. Don't forget to decrement your counter variable

Monday (12/6/10)

Warmup:

1. Initialize a counter variable i to 1
2. Create another variable old_i that starts at 1 also
3. Create a loop that runs up to 1000
   1. print out i and old_i on the same line (use a comma)
   2. save i into old_i
   3. increment i

• What happens when you execute the above code?
