簡單描述程式功能：

1.停用詞為csv檔案

2.原始檔為txt檔案

3.文字處理，將原檔案中出現的停用詞去除

程式碼實現：

1.檔案讀取，分詞，原始檔詞頻統計

python 讀取 西班牙語文字編碼：encoding='ISO-8859-1'

 1 #csv 檔案讀取，此處編碼為西班牙語
 2 def csvfile():
 3     file_path = os.path.join(upload_path, "SpanishStopWords.csv")
 4     with open(file_path,'r',encoding='ISO-8859-1') as f:
 5         reader = csv.reader(f)
 
 6         fieldnames = next(reader)#獲取資料的第一列，作為後續要轉為字典的鍵名 生成器，next方法獲取
 7         # print(fieldnames)
 8         data1=[]
 9         csv_reader = csv.DictReader(f,fieldnames=fieldnames) #self._fieldnames = fieldnames   # list of keys for the dict 以list的形式存放鍵名
10         for row in csv_reader:
11             dic1={}
 
12             for k,v in row.items():
13                 dic1[k]=v
14             data1.append(dic1)
15         return data1
16 #txt檔案讀取
17 def eachcount():
18     file_path = os.path.join(upload_path, "Alamo.txt")
19     txt = open(file_path, 'r', encoding='ISO-8859-1').read()
20     #分詞
21     txt = txt.replace('
 
,', ' ').replace('.', ' ')
22     txt = txt.split()
23     counts = {}  # 定義一個空字典型別
24     print(txt)
25     for word in txt:
26         counts[word] = counts.get(word, 0) + 1  # 獲取word當前有幾個，如果word不存在則為0
27     items = list(counts.items())
28     # 對一個列表按照鍵值對的兩個元素的第二個元素進行排序，由大到小的倒排，詞頻排序
29     items.sort(key=lambda x: x[1], reverse=False)
30     return items

2.顯示在原檔案中出現的所有停用詞

#顯示在原始檔中出現過的所有停用詞
@application.route('/listsearch/', methods=['GET', 'POST'])
def listsearch():
   file_path = os.path.join(upload_path, "SpanishStopWords.csv")
   txt = open(file_path, 'r', encoding='ISO-8859-1').read()
   txt = txt.split()
   filelist=txt
   # filelist=csvfile()
   filelist2=docu2()
   # wordlist=["my","name","boy","chirs","Dave"]
   result=[]
   result2=[]
   # for j in wordlist:
   #  for i in filelist:
   #     if i[0]== j :
   #        result.append(i)
   for j in filelist:
      for i in filelist2:
         if j== i :
            result2.append(j)
   return render_template('index.html',result2=result2)

前端程式碼展現：

<form action="/listsearch" method="get"  enctype="multipart/form-data">
         <button type="submit" value="submit">search</button>

     <p>result</p>
     {% for line2 in result2 %}
             <p>{{ line2}}</p>

{% endfor %}
    </form>
