Question

我正在开发非常庞大的档案系统。我的任务是用某些参数清理该系统。下面的方案支离破碎可带来想法。

import DirectoryWalker


extentions_to_delete = list([".rar",".doc",".URL",".js",".EXE",".mht",".css",".txt", ".cache", ".xml"])
extentions_to_copy = list([".jpg",".BMP",".GIF",".jpeg",".gif",".bmp",".png",".JPG"])

dw = DirectoryWalker.DirectoryWalker("/media/08247451247443AA/home/crap/")

def copy_advice(key, files):
    for ext in extentions_to_copy:
        if(ext == key):
            print str(len(files)) + " Files of type " + key + " should be coppied to the target folder."
            for file in files:
                copy_to = "/media/08247451247443AA/home/crap-pics/"

                moved = dw.move_file_to(file, copy_to, True)
                if not moved:
                    print file + " : not moved"

walks = dw.get_all_file_types()


for key in DirectoryWalker.Walk.store.keys():
    files = DirectoryWalker.Walk.store[key]

    copy_advice(key, files)

在<代码>上,以下代码为: 步行是一个简单的类别,有<条码> ,物体。

def get_all_file_types(self):

    extentions = []

    for dirpath,dirnames,filenames in os.walk(self.dir_name):
        for file in filenames:
            extentions.append(Walk(dirpath +"/"+ file))

    return extentions            

def move_file_to(self, file_path, copy_to, rename_if_exists= False):
        file_name = os.path.split(file_path)[1]

        target_file_name = copy_to + file_name;

        coppied = False

        if not os.path.isfile(target_file_name):
            coppied = True
            try:
                os.rename(file_path, target_file_name)
            except OSError:
                coppied = False
                print "Oops! Unable to rename : " + file_path + " to target : " + target_file_name

        if rename_if_exists:
            coppied = True
            file_name = "new_"+ file_name
            try:
                os.rename(file_path, target_file_name)  
            except OSError:
                coppied = False
                print "Oops! Unable to rename : " + file_path + " to target : " + target_file_name        

        return coppied

<代码>Walk

class Walk:

    store = dict([])

    def __init__(self, filename):

        self.file_ext = os.path.splitext(filename)[-1]
        self.file_name = filename

        if not (Walk.store.has_key(self.file_ext)):
            Walk.store[self.file_ext] = list() 

        Walk.store[self.file_ext].append(self.file_name)

但是,当方案执行时,它只能转移近10 400份档案。但人工计算表明,档案系统中应有13 400份档案。让我知道,我做了什么错?

A. 最新解决办法

After a careful investigations, I come out with result that there are many ambiguous file names in the target file system and those files were missing.

Answer 2

回答你的问题,为什么不首先采用更简单的法典来测试?

import os

all_files = []

for root, dirs, files in os.walk( /media/08247451247443AA/home/crap/ ):
    all_files.extend(files)

print len(all_files)

作为附带说明,请将“步行”改为defaultdict?
