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
The reason

is only a couple more

The real example would be more like:
name,age,country = itemgetter('name age country'.split())(x) # or any
of my above versions
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.
Learning tricks is useful,

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

Hi,
Let's take following perl code snippet:

($v1,$v2,$v3) = @myhash{qw(one two two)}; # -- line of interest
print $v1\n$v2\n$v2\n;

What about:
myhash={'one':1, 'two':2, 'three':3}

for a long list, you could try:
result = [mydict[k] for k in mydict]
or [mydict[k] for k in mydict.keys()]
or [mydict[k] for k in mydict.iterkeys()]
this won't give you the same order as your code though, if you want them
sorted you can use the sorted function:
[mydict[k]

or [mydict[k] for k in mydict.iterkeys()]
and the point of doing that instead of calling mydict.values() is what?
