Grizz[l]y,
I think the point is not about a sorted list or sorting in general It is
about reasons why maintaining a data structure such as a list in a program
can be useful beyond printing things once. There are many possible examples
such as having a list of lists containing a record where the third item is a
GPA for the student and writing a little list comprehension that selects a
smaller list containing only students who are Magna Cum Laude or Summa Cum
Laude.
studs = [
["Peter", 82, 3.53],
["Paul", 77, 2.83],
["Mary", 103, 3.82]
]
I've seen Mary, and she didn't look like a "stud" to me.
Of course, for serious work, some might suggest avoiding constructs like a
list of lists and switch to using modules and data structures [...]
Those who would recommend that approach do not appear to include Mr.
Rossum, who said:
Avoid overengineering data structures. Tuples are better than
objects (try namedtuple too though). Prefer simple fields over
getter/setter functions... Built-in datatypes are your friends.
Use more numbers, strings, tuples, lists, sets, dicts. Also
check out the collections library, eps. deque.[1]
I was nodding along with the people saying "list of lists" until I
reread this quote. A list of tuples seems most appropriate to me.
