示例调试：
import jieba
#jieba.lcut(s)是最常用的中文分词函数，用于精准模式，
#即将字符串分割成等量的中文词组，返回结果是列表类型。
k=jieba.lcut("全国计算机等级考试")
print(k)
#结果是列表类型，冗余性最大。
ls = jieba.lcut("全国计算机等级考试Python科目", cut_all=True)
print(ls)
#返回搜索引擎模式，该模式首先执行精确模式，然后再对其中长词进一步切分获得最终结果
ls = jieba.lcut_for_search("全国计算机等级考试Python科目")
print(ls)
#jieba.add_word()函数，顾名思义，用来向jieba词库增加新的单词。
jieba.add_word("Python科目")
ls = jieba.lcut("全国计算机等级考试Python科目")
print(ls)
