Python 批量处理文件

来源：互联网发布：网络攻防比赛编辑：程序博客网时间：2024/06/07 02:49

把一个文件下有许多文件夹,并且其中每个文件中又有很多文件(每个文件夹下的文件数量并不一定相同)（如下图）。

如1589文件夹下有三个文件（如下），但是1592文件夹下有4个文件：

现在我想把这些文件夹下的所有音频文件，转移到一个文件夹下，并修改文件名字，如下所示：

所以选择Python处理比较方便：

def eachFile(filepath):    pathDir =  os.listdir(filepath)    dic = {}    for file_name in pathDir:        child = os.path.join('%s/%s' % (filepath, file_name))        doc_path = os.listdir(child)        i = 0;        for each_document in doc_path:            i += 1            tmp = os.path.join('%s/%s' % (child, each_document))            shutil.copy(tmp, "/home/abner/Documents/world_wav")#copy tmp file to "/home/abner/Documents/world_wav"            #rename file name            os.rename("/home/abner/Documents/world_wav"+"/"+each_document, "/home/abner/Documents/world_wav"+"/"+file_name+"_"+str(i)+".mp3")        dic[file_name] = i

2、对于一个text文档，如下：

我现在想修改每一行的标号，并修改成如下样式：

可作如下处理：

    ########################################################    #           modify the text each row                   #    ########################################################    utts_path = "/home/abner/Documents/world_wav/utts.data"    write_modify_file = open("/home/abner/Documents/world_wav/Modify.data", 'w')    with open(utts_path, 'r') as f:        for line in f:            stuff = re.findall('[0-9]+', line)            get_file_name = stuff[0]            number = int(dic[get_file_name])            length = len(get_file_name)            for i in range(number):                line1 = line[0:2]+get_file_name+"_"+str(i+1)+line[2+length:]                write_modify_file.flush()                write_modify_file.write(line1)    write_modify_file.close()

all code:

# -*- coding: utf-8 -*-"""Spyder EditorThis is a temporary script file."""import osimport shutilimport numpy as npimport re################################################################      copy documents in different files to a given file      ################################################################def eachFile(filepath):    pathDir =  os.listdir(filepath)    dic = {}    for file_name in pathDir:        child = os.path.join('%s/%s' % (filepath, file_name))        doc_path = os.listdir(child)        i = 0;        for each_document in doc_path:            i += 1            tmp = os.path.join('%s/%s' % (child, each_document))            shutil.copy(tmp, "/home/abner/Documents/world_wav")#copy tmp file to "/home/abner/Documents/world_wav"            #rename file name            os.rename("/home/abner/Documents/world_wav"+"/"+each_document, "/home/abner/Documents/world_wav"+"/"+file_name+"_"+str(i)+".mp3")        dic[file_name] = i            ########################################################    #           modify the text each row                   #    ########################################################    utts_path = "/home/abner/Documents/world_wav/utts.data"    write_modify_file = open("/home/abner/Documents/world_wav/Modify.data", 'w')    with open(utts_path, 'r') as f:        for line in f:            stuff = re.findall('[0-9]+', line)            get_file_name = stuff[0]            number = int(dic[get_file_name])            length = len(get_file_name)            for i in range(number):                line1 = line[0:2]+get_file_name+"_"+str(i+1)+line[2+length:]                write_modify_file.flush()                write_modify_file.write(line1)    write_modify_file.close()     if __name__ == '__main__':    filePath = "/home/abner/Documents/USA/word"    eachFile(filePath)
