一、jieba的安装
同一般模块的安装过程，只需要在python的命令行里面输入
pip install jieba就可以了。我的环境是anaconda3，打开anaconda的命令行就可以了。
结果如下：
(base) C:\Users\DELL>pip install jieba
Collecting jieba

二、分词的实现
实现一个简单的微博文本分词。此处文本放置在weibo.xlsx中，代码如下：
#encoding='utf-8'
import xlrd
import jieba
data = xlrd.open_workbook("weibo.xlsx")
table = data.sheets()[0]
nrows = table.nrows
for i in range(nrows):
cut = jieba.cut(table.row_values(i)[5])
print(','.join(cut))运行部分结果为：
