The real example would be more like:

ouch.
if you do this a lot (=more than once), just wrap your dictionaries in a
simple attribute proxy, and use plain attribute access. that is, given
class AttributeWrapper:

That solution is very clever, and the inventor smart, but it's too
much out of standard and complex to be used in normal real code.

Thanks a lot for all your answers.
There's quite some things I learnt :-)
[v1,v2,v3] = ...
can be typed as
v1,v2,v3 = . . .
I also wasn't used to
map(myhash.get, ['one', 'two', 'two'])
itemgetter('one', 'one', 'two')(x)
I also didn't know
print "%(one)s\n%(two)s\n%(two)s" % mydict

How do I translate the second line in a similiar compact way to
python?
Below is what I tried.

this won't give you the same order as your code though, if you want them

What about:

Hi,
Let's take following perl code snippet:
%myhash=( one => 1, two => 2, three => 3 );
($v1,$v2,$v3) = @myhash{qw(one two two)}; # <-- line of interest
print "$v1\n$v2\n$v2\n";
How do I translate the second line in a similiar compact way to
python?
