python 進行結巴分詞 並且用re去掉符號

# 把停用詞做成字典
stopwords = {}
fstop = open('stop_words.txt', 'r',encoding='utf-8',errors='ingnore')
for eachWord in fstop:
    stopwords[eachWord.strip()] = eachWord.strip()  #停用詞典
fstop.close()

f1=open('all.txt','r',encoding='utf-8',errors='ignore')
f2=open('allutf11.txt','w',encoding='utf-8')

line=f1.readline()
while line:
    line = line.strip()  #去前后的空格
    line = re.sub(r"[0-9\s+\.\!\/_,$%^*()?;；:-【】+\"\']+|[+——！，;:。？、~@#￥%……&*（）]+", " ", line) #去標點符號
    seg_list=jieba.cut(line,cut_all=False)  #結巴分詞
    outStr=""
    for word in seg_list:
        if word not in stopwords:
            outStr+=word
            outStr+=" "
    f2.write(outStr)

    line=f1.readline()
f1.close()
f2.close()
