【原创】python MRJob -…

安装方式：easy_install mrjob

使用方法：

#!-*- coding: utf8 -*-"这段代码是使用"import re
import sys
import jieba

from mrjob.job import MRJob

word_re = re.compile(u"[\u4E00-\u9FA5]+")


class TestMrJob(MRJob):
    def mapper(self, _, line):        "统计每行"
        for word in word_re.findall(line.decode("utf8")):
            for new_word in jieba.cut(word):
                yield new_word.lower(), 1

    def reducer(self, word, counts):        "统计结果"
        yield word, sum(counts)


if __name__ == '__main__':   #此处注意：    data = TestMrJob.run()
    #sys.argv.append("data/2")
    #TestMrJob.run()
    

奇怪的是，tmp文件中的结果是这样子的....



碉堡了...
