jieba库去除停用词的代码

以下是使用jieba库去除停用词的示例代码：

import jieba
import jieba.analyse
import codecs
import sys

# 打开停用词文件，读取内容
stopwords_file = "stopwords.txt"
with codecs.open(stopwords_file, 'r', encoding='utf-8') as f:
    stopwords = f.readlines()
stopwords = [x.strip() for x in stopwords]

# 打开待处理文本文件，读取内容
input_file = "input.txt"
with codecs.open(input_file, 'r', encoding='utf-8') as f:
    text = f.read()

# 使用jieba进行分词
seg = jieba.cut(text)

# 去除停用词
seg_list = []
for word in seg:
    if word not in stopwords:
        seg_list.append(word)

# 输出结果
output_file = "output.txt"
with codecs.open(output_file, 'w', encoding='utf-8') as f:
    f.write(' '.join(seg_list))

代码中，使用`jieba.cut`方法进行分词，然后遍历分词结果，去除停用词。停用词以列表的形式存储在文件`stopwords.txt`中，每行一个停用词。最终结果以空格分隔的形式存储在文件`output.txt`中。
