• Due: Friday, May 29th no later than 5pm.
  • Submission instructions: complete the assigned number of activities in each of the assigned subsections of Chapter 10. You do not need to submit anything to Brightspace.
  • Deadline reminder: once this deadline passes, Runestone Interactive will no longer allow you to collect points for completing the activities.

Key ideas

From chapter 10:

  • A list is an ordered collection of items that can be of any type, e.g., ["Joy and Beauty of Data", 2020].
  • List creation, e.g., row = ["black", "blue", "orange"]
  • Determining list length: len
  • Accessing list elements
  • List memebership: in and not in
  • List concatenation: +
  • List repetition: *
  • List slices
  • Lists are mutable (unlike strings)
    • Replacement: row[0] = "yellow"
    • Deletion: row[1:3] = []
    • Deletion: del(row[0])
    • Insertion: row[2:2] = ["red", "magenta"]
  • List aliasing: row_2 = row
  • List cloning: row_2 = row[:]
  • List methods:
    • append(item)
    • insert(position, item)
    • pop() or pop(position)
    • sort()
    • reverse()
    • index(item)
    • count(item)
    • remove(item)
  • List append vs. list concatenation
  • For loop list traversal
    • by element
    • by position
  • Function parameters as lists
  • Pure functions
  • Functions returning lists
  • List comprehensions
  • Nested lists
  • Creating lists from strings using split()
  • Creating strings from lists using join()
  • Tuples


  • Complete the required number of activities for each subsection in Lists.

Grading - 10 points

  • 10 points - the required number of activities were completed for each subsection before the deadline.

Grading turnaround

This reading assignment will be graded with scores in Brightspace by office hours the following class day.

Optional activities

Activity 1

Work the following exercises:

  • Create a list called myList with the following six items: 76, 92.3, “hello”, True, 4, 76. Do it with both append and with concatenation, one item at a time.
  • Starting with the list of the previous exercise, write Python statements to do the following:
    1. Append “apple” and 76 to the list.
    2. Insert the value “cat” at position 3.
    3. Insert the value 99 at the start of the list.
    4. Find the index of “hello”.
    5. Count the number of 76s in the list.
    6. Remove the first occurrence of 76 from the list.
    7. Remove True from the list using pop and index.

Activity 2

  • The file contains information about the 10 most populous states.
  • Add a function to that calculates and returns the total population of the information passed into it. Print this value after the function returns it.
  • Modify the program to also print the percentage of the U.S. population that lives in the 10 most populated states.
  • Modify the populations variable to include information about whether each state is landlocked. Consider a landlocked state to be one that does not touch the Atlantic Ocean, the Pacific Ocean or the Gulf of Mexico.
  • Modify the program to also calculate and print the percentage of the population in the 10 most populated states that live in a landlocked state.
