Here's another choice, that's sometimes handy:
d = {1:'one',2:'two',3:'three'}
for k,v in d.items():
print k,v
1 one
2 two
3 three
I wouldn't recommend this for large dictionaries.
Yes, for large dictionaries, you should use:
for k, v in d.iteritems():
print k,

Calling dict.keys creates a list in memory of the keys to the dict.
Using the dict dir

I am attempting to understand the difference between two techniques
that use a for/in loop to iterate through entries in a dictionary
object. Copy/paste of interactive window illustrates.
>>> a = {}
>>> a.update({1:'a'})
>>> a.update({2:'b'})
>>> a
{1: 'a', 2: 'b'}
>>> for x in a:
... print x
