Wednesday (2/9/10)

Warmup:

  • Create strings for the following: "Animation", "Collision", "Keyboard", "Bouncing"
  • Write a program that prints the word that starts earliest in the alphabet
  • Test it works
  • Fix it so it works regardless of upper/lower case.
    Hint: to convert a string to lower case, call 'stringVar.lower()'
  • Test it works by changing the case of some of the words

Agenda

  • Submit Email Harvester to weblockers, if you haven't already - name it 'LAST-NAME_FIRST-NAME_HARVESTER.py'
  • If you haven't already: Demo and submit Dodge, if you haven't already. Today is the last class period to work on that (submit that too)
  • Complete HTTLACS: Ch7 exercises #5,6,7
    • Optional extension exercises from Ch 7: #1,2, 8-10
  • If you've done everything, study lists HTTLACS Ch 9. Do exercises 1-5.

Monday (2/7/10)

Warmup: Let's practice writing GASP code from scratch (15 minutes)

  1. Create a new program named gaspReview.py
  2. Open a graphics window
  3. Display a circle on the screen and save it as a variable named c
    • Be sure to create x and y variable coordinates for it
  4. Create a while loop that moves the circle across the screen to the right
    • If the circle's x-coordinate moves beyond the right side, change it's x-coordinate to 0
    • Randomize the y-coordinate between 0 and 600
  5. Test out the program
  6. Optional: if it runs, then try adding 2 more circles that have different speeds

Agenda

  • Demo/submit Email Harvester, if you haven't already
  • Demo Dodge (submit that too)
  • Study lists HTTLACS Ch 9
    • Complete exercises #1-5

Wednesday (2/3/11)

Warmup:

  • Build up a string
s = ""
x = 0
while x < 5:
  s = s + "a"
  x = x + 1
  print s
  • What is printed out after the code executes? (DO NOT USE A COMPUTER)

Agenda:

Tuesday (2/1/11)

Warmup:

  • Create a small program that counts the number of vowels in a string.
    • Example: "IceBerg" returns 3, and "IBM invented the mainframe!" returns 8.
  • If you're done, extend the program to count consonants too.
    • "IceBerg" has 4 and "IBM invented the mainframe!" has 14.

Agenda:

Friday (1/28/11)

Snow day

Wednesday (1/26/11)

Warmup:

  • Put the following sentence in a string:
Maybe there are greater aggravations in your life, but the symmetrical-on-the-outside, asymmetrical-on-the-inside USB connector has been a source of frustration since its introduction.
  • Write a small program that iterates through the string from the end and prints out every word in reverse order.
    • Hint: keep track of the index of the current word's last letter.
  • For bonus points, detect when words are separated by any punctuation mark, not just a space. Don't print the punctuation itself.

Agenda:

Monday (1/24/11)

Warmup:

  • Using python, create a string "Weʼre Building a Better Internet", and save it in variable sample.
  • Write expressions that:
    • Print the first character
    • Print the third character (the apostrophe)
    • Print the second from last character
    • Print the word 'Building'

Warmup:

  • Without using the computer, what does the following code display?
from gasp import *
begin_graphics(width=800, height=600, title="Question 23")

x = 0
while x < 100:
  Circle( (400 + x, 300), x )
  x = x + 10

update_when('key_pressed')
end_graphics()
