Problem Set 6 - Due Tue Nov 2 at 23:59


  1. Slides and notebooks from Lec 8 (While Loops), Lec 9 (Sequences and Loops), Lec 10 (List Processing Patterns), Lec 11 (Lists, Memory Diagrams & Mutable vs. Immutable Sequences), and Lec 12 (Nested Loops).
  2. Problems and solutions from Lab 5 (Loops), Lab 6 (More Loops), and Lab 7 (Memory Diagrams and Nested Loops).
  3. Think Python, Chapter 7 covers iteration, and Think Python, Chapter 10 covers lists.


The instructions for each task and their specific requirements are laid out on the following pages:

About this Problem Set

This problem set will give you practice with list memory diagrams and nested loops as well as more practice with sequences (strings and lists), operations on sequences, and regular loops on sequences.

If you want to find a partner to work with for this problem set, use this Google Sheet to do so.

Note that you may not work with different partners on different tasks in this problem set. If you are working with a partner on one task, you must either work individually or work with that same partner on any other tasks where a partner is allowed.


Time Estimate

To help you plan how long you need to spend on this problem set, we have some guidelines based on how long students spent on these tasks last semester (please fill out your time estimates to help students in future semesters). Note that this semester, due to the large number of new tasks, these numbers are often just estimates.

When you've been working on a task for about 2.5 hours, you should evaluate whether you are making efficient progress, and make use of some of the class resources available to you, like help-room hours or office hours. If you've been working on one task for 4 hours and still have a ways to go, you should definitely get some help with it.

The entire problem set will probably take you something like 7–10 hours of programming, plus another half hour to hour of reading, although some students take more or less time than that.
