4.04 is overkill. Proposed changes for your review. List comprehensions.

Discussed in #370

4.04 goes through nested loops and lists a second time for 2 days. 4.03 also covers nested loops. 4.05 covers debugging nested loops. All together that is 5 days. Nested loops don't deserve that much attention in my opinion.

I moved the Tic-Tac-Toe game to Unit 3 because it doesn't need loops and it certainly doesn't need nested loops. #358 If the motivation behind 5 days of nested loops is Tic-Tac-Toe then it isn't required.

Instead I have proposed a change to 4.03 making a one day lecture and lab on nested loops and nested lists. #367

I would now like to propose changing lesson 4.04 to cover list comprehensions. List comprehensions are a vital piece of Python that we don't seem to cover.

Here is my slide show. https://docs.google.com/presentation/d/1pZHqtiT0GV-h5TIXybDXklweRxKqLloQNCTFoiOF_C8/edit?usp=sharing You may notice it references changes I made to 4.02. #365

Assignment looks like this:

Lab 4.04 - List Comprehension

Part 1

The goal of this lab is to practice using list comprehensions. Add a list comprehension to the starter code.

The functionmultiply_list(numbers, multiplier) will return a new list where each number in the numbers list will be multiplied by multiplier.

Starter Code

numbers = list(range(1,11)) # 1 to 10


def multiply_list(numbers, multiplier):
    return[] # <-- put a list comprehension here


print(numbers)
print(multiply_list(numbers, 3))

The output should look like this:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
[3, 6, 9, 12, 15, 18, 21, 24, 27, 30]
