Wednesday (5/19/10)
Warmup:
- Create a new file named advancedListEx.py
- import random at the top b/c we will be creating random numbers
- Create an empty list named randomNumbers (an empty list is just brackets [])
- Write a loop that runs 10 times (HINT: write a loop that prints out 0 to 10)
- Inside the loop, generate a random number using random.randint(0,100) and store it in a variable named r
- Append r to randomNumbers
- Don't forget to increment your loop's counter variable
- After the loop, print out randomNumbers
Agenda:
- Demo Python List Exercises
- Begin working on Advanced Python List Exercises
Monday (5/17/10)
Warmup:
- Create a list that contains the following numbers: 8, 6, 7, 5, 3, 0, 9
- Create a variable named total that contains the value 0
- Initialize a counter variable named x to 0
- Write a while loops that runs while x is less than the length of your list
- Inside your loop, add the current element (yourList[x]) to total
- Increment your loop counter x
- Print the total variable, which should now be the sum of all the numbers
Agenda:
- Warmup Review
- Why do we use lists and loops? Use your warmup again, but instead, make the list hundreds of numbers
- [4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7, 4, 6, 3, 7, 6, 8, 5, 2, 3, 5, 2, 6, 7]
- Adding and deleting from a list
- Complete and demo Python List Exercises
- Begin working on Advanced Python List Exercises

Monday (5/3/10)
Warmup:
- s = "H e l l o , w o r l d !"
- Create a variable named new_s that contains an empty string
- Write a while loop where the counter variable x starts at 0 and goes up to len(s)
- Check if the current letter at x (s[x]) is NOT a space
- Add the current letter (s[x]) to new_s
- Increment x
- Check if the current letter at x (s[x]) is NOT a space
- What does the above code produce?
