IIUC，用途：
def lowest(*args):
ratings = {}
for d in args:
for k, v in d.items():
if k in ratings:
ratings[k] += v
else:
ratings[k] = v
return min(ratings, key=lambda k: ratings[k])
或者，
from collections import defaultdict
def lowest(*args):
ratings = defaultdict(int)
for d in args:
for k, v in d.items():
ratings[k] += v
return min(ratings, key=lambda k: ratings[k])
調用函數：
print(lowest(alice_ratings, bob_ratings, alonzo_ratings, turing_ratings))
這打?。?/p>
