This homework is worth only 1 point (regular assignments are worth 2).
Download hw08.zip. This homework contains an AutoStyle assignment.
You must run
python3 ok --submit and complete the AutoStyle assignment to
receive full credit for this homework. The AutoStyle assignment will take about
1 hour and must be completed by yourself in a single sitting.
Submission: When you are done, submit with
python3 ok --submit.
You may submit more than once before the deadline; only the final submission
will be scored. Check that you have successfully submitted your code on
See Lab 0
for more instructions on submitting assignments.
Using OK: If you have any questions about using OK, please refer to this guide.
Readings: You might find the following references useful:
The following problem will be used as part of the AutoStyle study which you can find more information about on Piazza.
Question 1: Deep Length
A list that contains one or more lists as elements is called a deep list. For
[1, [2, 3], 4] is a deep list.
A deep list of integers is a list containing either integers or deep lists.
deep_len, which takes in a deep list of integers
lst. It returns
the number of integers that appear anywhere within
Hint: you can check if something is a list by using the built-in
function. For example,
>>> type(3) == list False >>> type([1, 2, 3]) == list True
def deep_len(lst): """Returns the deep length of the list. >>> deep_len([1, 2, 3]) # normal list 3 >>> x = [1, [2, 3], 4] # deep list >>> deep_len(x) 4 >>> x = [[1, [1, 1]], 1, [1, 1]] # deep list >>> deep_len(x) 6 >>> x =  >>> for i in range(100): ... x = [x] + [i] # very deep list ... >>> deep_len(x) 100 """ "*** YOUR CODE HERE ***"
Use OK to test your code:
python3 ok -q deep_len
Question 2: Run AutoStyle
Once you have passed all the tests, invoke AutoStyle by running the command:
python3 ok --style -q deep_len
AutoStyle will provide hints to help improve code style and composition. The process will take about 1 hour and must be completed in a single sitting.
When running AutoStyle, please don't place any
