Objectives

  • You will learn to create lists
  • You will learn to access elements (things) in a list
  • You will learn to traverse (walk through) a list using a loop

Resources

Directions

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


  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
  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
  4. Write a loop that goes from 0 to 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)
