python 如何实现 Key 对应的 value 不断加一?

[Newyorkcity]

record = {'example' : 0}
for i in range(0,10):
　　 record['example'] = record['example']所对应的 value+1

关键问题在于「 record['example']所对应的 value 」该怎么写?

[loveersoldier]

record['example'] += 1

[NaVient]

record['example']就是对应的 value 啊

[beviniy]

from itertools import Counter

突然觉得很囧

[wind3110991]

record = {'example' : 0}
for i in range(0,10):
　　 record['example'] = record['example'] + 1

print record['example']

[romanticbao]

record = {}
DEFAULT_VALUE = 0
for item in data_list:
record[item] = record.get(item, DEFAULT_VALUE) + 1
