python 遍历文件夹子文件夹，批量生成txt

import os
import os.path

def createList(root_dir, class_list, info_name):
    info = open(info_name, "w")
    for class_name, label in class_list:
        class_path = root_dir + "/" + class_name
        for name in os.listdir(class_path):
            info.write(class_path + "/" + name + "\t" + str(label) + "\n")
    info.close()
        

if __name__ == "__main__":
    #class_list = [(str(i), i) for i in range(7)]   这个是文件夹名字为 1 2等情况
	#class_list = [('latin','latin')]
	# class_list = [('Arabic_0','Arabic_0')]
	info_name = os.getcwd()
	#print info_name
	#root_dir = os.getcwd()+"/Train"
	root_dir = os.getcwd()+"/Test"
	class_list = []
	FileName = []
	FileNames = os.listdir(root_dir)  这种方法文件夹名为任意值情况
	ErrorFileName = 'error' #error file
	print ErrorFileName
	label = 0
	if(len(FileNames)>0):
		for fn in FileNames:
			print fn 
			if fn != "error":  这里用于判断 error 文件夹不用批处理
				FileName = [fn,label]
				label = label + 1
				class_list.append(FileName)
	label = 0
	#info_name = os.getcwd() + "/train-list.txt" 
	info_name = os.getcwd() + "/test-list.txt"
	createList(root_dir, class_list, info_name)

    # root_dir = os.getcwd() + "/Train"
    # info_name = os.getcwd() + "/train-list.txt"
    # createList(root_dir, class_list, info_name)
                       
    #RootDir = os.getcwd()+"/Test" 
	# RootDir = os.getcwd() 
	# for parent,dirnames,filenames in os.walk(RootDir):
		# for dirname in dirnames:
			# print "parent is:" + parent
			# print "dirname is" + dirname
		
		# for filename in filenames:
			# print "parent is:" + parent
			# print "filename is:" +filename
			# print "the full name of the file is:" + os.path.join(parent,filename)
	
	# RootDir = os.getcwd()+"/Test" 
	# FileList = []
	# FileName = []
	# FileNames = os.listdir(RootDir)
	# if(len(FileNames)>0):
		# for fn in FileNames:
			# FileName = [fn,fn]
			# FileList.append(FileName)
	# print FileList

可以参考下边

import  os

def  GetFileList( dir , fileList):
    newDir  =  dir
    if  os.path.isfile( dir ):
        fileList.append( dir .decode( 'gbk' ))
    elif  os.path.isdir( dir ):
        for  s  in  os.listdir( dir ):
            #如果需要忽略某些文件夹，使用以下代码
            #if s == "xxx":
                #continue
            newDir = os.path.join( dir ,s)
            GetFileList(newDir, fileList)
    return  fileList

list  =  GetFileList( 'D:\\workspace\\PyDemo\\fas' , [])
for  e  in  list :
    print  e
