Named formatting in python print statements.

named_formatting.py

data = dict(state='active', canonical_name='un#ep')
print('Endpoint %(canonical_name)s is %(state)s' % data)
print('Endpoint {canonical_name} is {state}'.format(**data))

foo, bar = 'foo', 'bar'
print('%(foo)s%(bar)s' % locals())
print('{foo}{bar}'.format(**locals()))
print('{foo}{bar}'.format(foo='foo', bar='bar')) # how much faster is % formatting?
