Dołącz listę łańcuchów w Pythonie i zawiń każdy łańcuch w cudzysłowy

Mam: 

words = ['hello', 'world', 'you', 'look', 'nice']

Chcę mieć: 

'"hello", "world", "you", "look", "nice"'

Jaki jest najprostszy sposób, aby to zrobić z Pythonem?

>>> words = ['hello', 'world', 'you', 'look', 'nice']
>>> ', '.join('"{0}"'.format(w) for w in words)
'"hello", "world", "you", "look", "nice"'

Można również wykonać pojedyncze format wywołanie 

>>> words = ['hello', 'world', 'you', 'look', 'nice']
>>> '"{0}"'.format('", "'.join(words))
'"hello", "world", "you", "look", "nice"'

Aktualizacja: niektóre benchmarking (wykonywane na mbp 2009): 

>>> timeit.Timer("""words = ['hello', 'world', 'you', 'look', 'nice'] * 100; ', '.join('"{0}"'.format(w) for w in words)""").timeit(1000)
0.32559704780578613

>>> timeit.Timer("""words = ['hello', 'world', 'you', 'look', 'nice'] * 100; '"{}"'.format('", "'.join(words))""").timeit(1000)
0.018904924392700195

Więc wydaje się, że format jest rzeczywiście dość drogie

Update 2: po komentarzu @JCode, dodanie map aby upewnić się, że join będzie działać, Python 2.7.12 

>>> timeit.Timer("""words = ['hello', 'world', 'you', 'look', 'nice'] * 100; ', '.join('"{0}"'.format(w) for w in words)""").timeit(1000)
0.08646488189697266

>>> timeit.Timer("""words = ['hello', 'world', 'you', 'look', 'nice'] * 100; '"{}"'.format('", "'.join(map(str, words)))""").timeit(1000)
0.04855608940124512

>>> timeit.Timer("""words = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] * 100; ', '.join('"{0}"'.format(w) for w in words)""").timeit(1000)
0.17348504066467285

>>> timeit.Timer("""words = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] * 100; '"{}"'.format('", "'.join(map(str, words)))""").timeit(1000)

Możesz spróbować tego: 

str(words)[1:-1]
