CS1 - 0910 - May

From WLCS

Thursday - Monday (5/27/10 - 5/31/10)

Friday - Tuesday (5/21/10 - 5/25/10)

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:

Monday (5/17/10)

Warmup:

  1. Create a list that contains the following numbers: 8, 6, 7, 5, 3, 0, 9
  2. Create a variable named total that contains the value 0
  3. Initialize a counter variable named x to 0
  4. 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
  5. 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

Agenda:

Tuesday (5/11/10)

Warmup - Regular:

Monday (5/3/10)

Warmup:

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