python常用代码块 | python 压缩包解压后提取txt文字

import os,time,subprocess

#获取当前目录
baseDirPath = os.getcwd()   
print(baseDirPath) 

#获取当前时间
current_time = time.strftime('%H_%M_%S', time.localtime())
print(current_time)

#解压程序地址
sz = baseDirPath + r'\7-Zip\7z.exe'
print(sz)

#--------------压缩包地址----------------
rarDir = r'D:\python\pyapp\unzip\File'

txtcacheDir = baseDirPath + r'\txtCache'
txtOutput = baseDirPath + '\\' + current_time + '.txt'

def txtWriter(txt_path, wd_info):

                    if 'AAA:' in line:
                        #print(line)
                        txtWriter(txtOutput, line)
                f.close()
                #删除文件        
                os.remove(txtFilePath)

获取文件夹下TXT文件，并读取其中文字写到目标文件中

import os,time
#单纯读取含txt的文件夹
#获取当前目录
baseDirPath = os.getcwd()   
print(baseDirPath) 

#获取当前时间
current_time = time.strftime('%H_%M_%S', time.localtime())
print(current_time)

#---------------------文件夹
txtcacheDir = r'D:\python\pyapp\unzip\txt'

txtOutput = baseDirPath + '\\' + current_time + '.txt'

def txtWriter(txt_path, wd_info):
  f = open(txt_path, 'a+', encoding = 'utf-8', errors = 'ignore')
  f.write(wd_info + '\n')
  f.close()
 
#逐一读取txt文件夹下的所有文件
txtList = os.listdir(txtcacheDir)
for txtFile in txtList:
    print(txtFile)
    if txtFile.split('.')[-1].lower() == 'txt':
        txtFilePath = txtcacheDir + '\\' + txtFile
        print(txtFilePath)

        #读取
        f = open(txtFilePath, encoding='utf-8', errors='ignore')
        content = f.readlines()
        for line in content:
            if 'AAA:' in line:
                #print(line)
                txtWriter(txtOutput, line)
        f.close()
