Convert every dictionary value to utf-8 (dictionary comprehension?)

Question

I have a dictionary and I want to convert every value to utf-8. This works, but is there a "more pythonic" way?

            for key in row.keys():
                row[key] = unicode(row[key]).encode("utf-8")

For a list I could do

[unicode(s).encode("utf-8") for s in row]

but I'm not sure how to do the equivalent thing for dictionaries.

This is different from Python Dictionary Comprehension because I'm not trying to create a dictionary from scratch, but from an existing dictionary. The solutions to the linked question do not show me how to loop through the key/value pairs in the existing dictionary in order to modify them into new k/v pairs for the new dictionary. The answer (already accepted) below shows how to do that and is much clearer to read/understand for someone who has a task similar to mine than the answers to the linked related question, which is more complex.

Answer 1

Python 3 version building on that one answer by That1Guy.

{k: str(v).encode("utf-8") for k,v in mydict.items()}

Answer 2

Use a dictionary comprehension. It looks like you're starting with a dictionary so:

 mydict = {k: unicode(v).encode("utf-8") for k,v in mydict.iteritems()}

The example for dictionary comprehensions is near the end of the block in the link.
