Directions

Create a file name "ch9_yourLastName.py". In your file, complete the following exercises:

List Basics:

  1. Create a list named wordList that contains the following words: "washington", "lee", "generals", "arlington", "virginia"
  2. Print out the first element in wordList
  3. Print out the length of the list by using len(wordList)
  4. Print out the last element in wordList by using wordList[len(wordList)-1]
  5. Print out the word "generals" in the list

Lists with loops:

  1. Create a list named numList with the following numbers 3, 1, 7, 6, 4, 1, 1, 5, 4, 7, 9, 0, 9, 7, 7, 43, 2, 6, 87, 67, 4, 2, 532
  2. Print out the last element in numList using len(numList)-1
  3. Print out the middle element in numList using len(numList) // 2 (the double division sign is intentional--it automatically rounds down)
  4. Write a loop that goes from 0 up through len(numList)-1 that prints out ALL the elements in numList
  5. Write a loop that goes from len(numList)-1 down through 0 and prints numList in reverse order
  6. Write a loop that prints out all the numbers in numList that are greater than 10
  7. Write a loop that prints out all the numbers in numList that are even (HINT: if numList[x]%2 == 0)

Adding and removing elements:

  1. Create an empty list [] named myList
  2. Add the following words to myList by using myList.append( WORD ) for each of the words:
    • "The"
    • "quick"
    • "brown"
    • "fox"
    • "jumps"
    • "over"
    • "the"
    • "lazy"
    • "dog"
  3. Print myList to see if all the words were added
  4. Delete the word "brown" from the list by using del myList[ LOCATION ]
  5. Now delete the word "over"
  6. Print myList again to see if the right words were deleted
  • When you are done, copy and paste the above code into a Google Doc and share it with Mr. Bui via Google Classroom
