I think I'll enjoy doing this. As a teacher with less free time, these tasks seem short and will keep my brain "puzzling" over code without the stress of a high priority project looming in the background.

So far I've got a time of around 1 second on the first challenge. It's nice to be able to practice my profiling and see how low I can get it!

Hint: python -c 'help(max)'

Good tip, I defaulted to using sorted which is almost as fast (but not quite)

I don't like the solution template they propose because it will likely stall users from creativly solving the problem. I also don't think this is an idomatic solution to the problem in a pythonic way.

You're going from file->list->for loop when you can just go file->for loop.

If anyone is interested in something for comparison, here's what it would look like in k6 (http://kparc.com):

    v: 1 2 3 4 5 8 10
    l: "|"\"eaoinrtlsu|dg|bcmp|fhvwy|k|jx|qz"
    d: !/+,/l,\:'v
    t@*>(+/d@_:)'t:0:"dictionary.txt"
First three lines are constructing the dictionary the template in this problem hands to you, and the last line loads the file and finds the item with the maximum scrabble dictionary score.

@gravypod, that's actually a really good point mate! The last thing we want to do is limit creativity. Do you think it'd be more beneficial to just provide a blank file in the individual challenges rather than a template?

This was our first real attempt at an open challenge. We were wondering how best to push it. The idea behind the template was to simplify it for the newer coders, almost like a hint.

Definitely loving the feedback! It's the only way to learn!

This would be the readable perl5 solution:

    my %scrabble_scores = (
       1 => [qw( E A O I N R T L S U )], 
       2 => [qw( D G )],
       3 => [qw( B C M P )],
       4 => [qw( F H V W Y )],
       5 => [qw( K )],
       8 => [qw( J X )],
      10 => [qw( Q Z )]);
    my $dict = "/usr/share/dict/words";
    open my $d, " 0);
    while () {
      my $score = 0;
      chomp;
      for my $c (split//) {
        $score += $a{uc($c)};
      }
      @maxscore = ($_ => $score) if $score > $maxscore[1];
    }
    print "$maxscore[0] => $maxscore[1]\n";
Arguable more readable than python
