I'm not an advanced Python user, so there may be more efficient or elegant
solutions. The code below is a Python 2.5 equivalent.
Jamal
hash = {'John': 40, 'Michael': 40, 'Joe': 30}
keys = sorted(hash.keys(), reverse = True)
keys = sorted(keys, lambda x, y: cmp(hash[x], hash[y]))
for key in keys: print key + ', ' + str(hash[key])

Subject: Re: python question
The Windows msi installer for python from python.org contains a chm help
file for python 3, or at least this is how it is named.
I haven't started to read it though.
But I have a question regarding python.
I have started to read the book "Perl to python migration" hoping to
understand it better, but I am pretty confused of how python does the
sorting, or at least about how it is explained in that book that might be
old, because it talks about python 2.0.
For example, if I have a perl hash, or python dictionary like:
my %hash = (Joe => 30, John => 40, Michael => 40);
and I want to sort it for example by the values of the hashin increasing
order, then by the keys of the hash in decreasing order, in perl I would
need to do just:
foreach my $key(sort {$hash{$a} <=> $hash{$b} or $b cmp $a} keys %hash) {
print "$key, $hash{$key}\n"; }
This would print:
Joe, 30
Michael, 40
John, 40
Can you tell me how to do this in python? I hope there are newer ways of
doing this more easier than what I read in that book.
And I would also like to know which is the prefered ORM, the prefered
templating systems, form manager(s), web framework... (although I think it
is Zope), so if you have used them, please tell me.
