You may collaborate on this homework with AT MOST one person, an optional "homework buddy".
MAY ONLY BE TURNED IN IN THE LECTURE/LAB LISTED ABOVE AS THE DUE DATE,
OR IF APPLICABLE, SUBMITTED ON GRADESCOPE. There is NO MAKEUP for missed assignments;
in place of that, we drop the lowest scores (if you have zeros, those are the lowest scores.)
Please read Perkovic 4.1-4.2 (Strings, Formatting). Then complete these problems.
(10 pts) Please fill in the information at the top of this homework sheet, including your name and umail address. If the other two items apply, please fill them in as well. Please do this every single time you submit homework for this class. It is important to fill in both name and umail every time, since handwriting is sometimes difficult to decipher. Having both helps us ensure you get credit for your work.
DO NOT staple, paper clip, spit-fold-and-tear, or do ANYTHING that would make it difficult to automatically feed your paper through a scanner.

(5 pts) In Python, how do we define a string that consists of more than one line of text?
(5 pts) For the Python code in the left box, write the output in the right box
the_list = ["8","16","24","32"] for course in the_list: print(course, end="|")
When you import the module
time, the function
time.time()gives “seconds since the epoch”, while
time.gmtimegives a representation of the time in UTC.
(5 pts) What is “the epoch”?
(5 pts) What is UTC?
(5 pts) If you want the local time instead of UTC, what function of the
timemodule do you call instead of
(5 pts) As shown on p. 106, if you enter
import timeat the
>>>prompt, then enter the following:
>>> time.strftime('%A %b/%d/%y %I:%M %p', time.localtime())
the resulting output is the current date and time in the format:
Tuesday Oct/24/17 11:59 AM
Using the table of values on p. 107 as a reference, how would you change the call to
strftimeabove to get the date in this format:
