>>d = dict(a=2, b=1)
for key in sorted(d):

.... print key, d[key]
....

b 1

That's not a solution to "sort the dict"; that's getting a particular
representation of the dict. It's likely the original poster wants the
equivalent to list.sort() instead of a one-time output of the
contents.

Yes, but as others have pointed out, you can't get that with a standard
Python dict. 99% of the time when a poster asks about how to sort a
dict, their problem can be solved by simply sorting the dict keys or values.
