IB Computer Science 1

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:

• Demo E-mail Harvester Assignment - due by end of class today.
• Once you've demoed email harvester, return to Dodge game - due end of class Monday 2/7.
• If you've completed Dodge, complete HTTLACS: Ch7 #1,2, 5-10
• Finally, read 'Introduction to Lists': HTTLACS: Ch9 #1-5
• Closure
  • Complete evaluation form

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:

• Quick review of strings: refer to Media:Strings_Python.ppt if needed.
• Spend 30 minutes working on the E-mail Harvester Assignment
• Spend 30 minutes working on the Dodge game, if not complete.
• Closure: Complete evaluation form

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:

• Work on the E-mail Harvester Assignment - demo when complete.
• Once you're done, you can return to working on the Dodge game

Monday (1/24/11)

  • Print the second from last character
  • Print the word 'Building'

Agenda:

• Demo completed Dodge game
• Submit Python String Exercises if you haven't already done so.
• Work on the E-mail Harvester Assignment
