[Tutor] high score lists

[D. Hartley]

my apologize to Alberto - instead of replying to the whole list, I
accidentally replied only to him! Here are my replies, for anyone else
who might be reading/interested:


This is what I have so far:

high_scorelist = [(1000,"Denise"), (945,"Denise"), (883,"Denise"),
                 (823,"Grant"), (779,"Aaron"), (702,"Pete"),
                 (555,"Tom"), (443,"Tom"), (442,"Robin"), (404,"Pete")]

userscore = (441,"Joe")

def add_score(userscore):
   if userscore[0] > high_scorelist[len(high_scorelist)-1][0]:
       print "You made the high score list!"
       high_scorelist.append(userscore)
       high_scorelist.sort(reverse=True)
       del high_scorelist[len(high_scorelist)-1]
       return high_scorelist
   else:
       print high_scorelist

I had to enter in the variable for "userscore" like that, when I add a
tuple directly into the add_score function, it seems to delete the
last item in the list (i.e., the one I just added) BEFORE it sorts it
(i.e., removing the lowest score).  I have no idea why this is.  But
if I define userscore = (465,"Jane"), for instance, and then run
add_score(userscore), it'll change and print my 10-person high score
list, just like I want it to.  But the problem remains both how I
could display this (if even just in the python window), and how I
could get my program to create the tuple to plug in there.  (I also
just ended up writing the list like [score,user] because I couldnt
figure out how to get it to sort by the second half of the tuple.  I
need a better tutorial book, I think!)

Thanks again for any suggestions/pointers!

and  a question about sorting (either way):

 I am trying it out with a list of tuples right now. The first problem
 I ran into is that when i sort it (scorelist.sort(reverse=True)), it
 sorts by the person's name (the first entry), and not by the score.
 plus I'm not quite sure yet how I'd get the user's name or score
 *into* the list - without manually adding it as a tuple? Since I can't
 do something like ... ("John", 100) .... username = "John", userscore
 = 100, if userscore > lowestuserscore etc.

 With a dictionary, could I point something like username to key and
 something like userscore to value?

 But then the problem with dictionaries comes back around to sorting
 too: Can I sort (and then display) a dictionary?

 Also, thanks for the idea about the pickle module - where can I get
 that and documentation for it?

 Thank you guys for your suggestions, and I apologize for the "newbie"
 level of my questions.  I am trying to answer as much as I can from
 the tutorial materials I have here, but they don't always explain
 everything (such as what the "cmp=None, key=None" means in the ( )
 helper of the .sort function.  I figured reverse=True/False out by
 playing with it).

 I really appreciate all this help! I'm trying to make this game for a
 birthday joke for the person who is teaching me programming, so
 obviously I cant ask him for help!

 :)  Denise
