Python 3.2: How to pass a dictionary into str.format()

I've been reading the Python 3.2 docs about string formatting but it hasn't really helped me with this particular problem.

Here is what I'm trying to do:

stats = { 'copied': 5, 'skipped': 14 }
print( 'Copied: {copied}, Skipped: {skipped}'.format( stats ) )

The above code will not work because the format() call is not reading the dictionary values and using those in place of my format placeholders. How can I modify my code to work with my dictionary?
