批量提取多个TXT 文本中指定内容 导出为一个TXT

Question

多个TXT 批量提取文本中的某些内容 导出为一个txt 文本或者别的格式 该怎么实现

Answer 1

os.listdir(path)遍历文件夹中多个TXT 用正则提取文本中的指定内容

你题目的解答代码如下：

#-*- coding:utf-8 -*-
import os
import re
rs = ""
path = r"E:/xxx" #读取txt文件的目录路径
FileNames=os.listdir(path)
for fn in FileNames:
    if fn.endswith('.txt'):
        fullfilename=os.path.join(path,fn)
        print(fullfilename)
        with open(fullfilename, 'r', encoding='utf-8') as fileObj:
            text = fileObj.read()
        card = re.findall(r'Card:(.+)',text)
        exp = re.findall(r'Exp:(.+)',text)
        coding = re.findall(r'Coding:(.+)',text)
        zip = re.findall(r'zip:(.+)',text)
        if len(card)>0 and len(exp)>0 and len(coding)>0 and len(zip)>0:
            rs += card[0] + "|" + exp[0] + "|" + coding[0] + "|" +zip[0] + "\n"
print(rs)
with open(r'data.txt', 'w', encoding='utf-8') as fileObj:
    fileObj.write(rs)
