python fuzzywuzzy 模糊匹配，计算相似度

from fuzzywuzzy import fuzz
from fuzzywuzzy import process

1:简单匹配

a = fuzz.ratio('this is a shot','this is a shat')

Out[37]: 93

2:非完全匹配

b = fuzz.partial_ratio('this is a shot','this is o shot')

Out[38]: 93
3:忽略顺序匹配

d = fuzz.token_sort_ratio('我是谁？我在哪？','我在哪？我是谁?')

Out[40]: 100
4:去重子集匹配

e = fuzz.token_set_ratio('this is a shot','this is is a shot')

Out[42]: 100

5:返回模糊匹配的字符串和相似度，如果不需要全部数据，只要
其中几个，可以最后设置条件limit = n 即可

choices = ["Atlanta Falcons", "New York Jets", "New York Giants", "Dallas Cowboys"]
f = process.extract("New York Jets",choices)

Out[44]:
[(‘New York Jets’, 100),
(‘New York Giants’, 79),
(‘Atlanta Falcons’, 29),
(‘Dallas Cowboys’, 22)]

模糊查找匹配字符串和相似度

g = process.extractOne('Cow',choices)

Out[46]:
(‘Dallas Cowboys’, 90)
