We will list methods from any classes that you may need to use
on the exam (like methods from str, lst, Circle, etc.). We do
not expect you to memorize the methods from all classes we have used.
However, you should know how to use the methods given our listing of
them (i.e. we will not tell you how to use the methods during the exam).
For example, we may list something like this for the file class:
open(fname): open a file specified by fname for reading. returns a new file object.
f.close(): close the file f.
f.readline(): returns the next line read from the file f including the newline character \n.
f.readlines(): returns a list of all the lines in the file f. each line contains
a newline character (\n) as the last character in the line.
