i中有200个文本文件。想要删除特殊字符的空白并在python中找到查找bigram和trigram。

Question

import os

dir=os.getcwd()
print(dir)
dir1=os.path.join(dir,"test")
filename=os.listdir(dir1)
bad_chars = [';', ':', '!', "*","#","%"]
for i in filename:
    filepath=os.path.join(dir1,i)  #  the path
    file=open(filepath,"r",encoding="utf8") #open first text file
    read_=file.read()
    fields = read_.split(" ")
    print(fields)
    file1=open(filepath,"w",encoding="utf8")
    file2=open(filepath,"a",encoding="utf8")
    for j in range(len(fields)):        
        for p in bad_chars :
            fields[j].replace(i,' ')
            file2.write(fields[j])
            print ("Resultant list is : " , fields[j])
file.close()
file1.close()
file2.close()

我正在尝试从所有200个文本文件中删除特殊字符

这是我找到的bigram的代码

import nltk
from collections import Counter
fo = open(r"Aacha_S_001_0_E1800.txt",errors='ignore',encoding='utf8')
fo1 = fo.readlines()
for line in fo1:
    bigm = list(nltk.bigrams(line.split()))
    bigmC = Counter(bigm)
    for key, value in bigmC.items():
       # print(key, value)
        out_put = str(key) + " was found = " + str(value) + " times" + "\n"
        with open('Test1.txt','a',encoding='utf8') as f:
            f.write(out_put)       
            f.close()        
print(".............done.............") 

想要在一个程序中同时使用两个代码先感谢您我的名字叫eshan。输出我的名字出现1名称，出现1是，提前发生1根据文字，发生次数可以大于1

import os dir = os.getcwd（）print（dir）dir1 = os.path.join（dir，“ test”）filename = os.listdir（dir1）bad_chars = [';'，'：'，'！ '，“ *”，“＃”，“％”]表示文件名中的i：filepath = os.path.join（dir1，i）＃路径...
