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)
Warmup:

- Print the third character (the apostrophe)
- 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
