Python shutil.copytree（）可以跟踪复制状态 [英] Python shutil.copytree() is there away to track the status of the copying

问题描述

我的目录中有很多光栅文件（600+），需要将其复制到新位置（包括其目录结构）。有没有一种方法可以使用shutil.copytree（）来跟踪复制状态？通常对于文件，我将使用以下代码，但不确定如何使用shutil.copytree（）：

  os.walk（sourceFolder）中的currentFolder，subFolder，fileName：文件名中i的
：如果i.endswith（。img）：
：
打印 copying {}。format（ i）
 shutil.copy（os.path.join（currentFolder，i），outPutFolder）
  

https://docs.python.org/2/library/shutil.html#copytree-example

下面也粘贴了示例：

 从shutil导入copytree 
导入日志
 
 def _logpath（路径，名称）：
 logging.info（'正在％s'％路径中工作）
 return []＃不会被忽略
 
 copytree（源，目标，ignore = _logpath）
  

I have a lot of raster files (600+) in directories that I need copy into a new location (including their directory structure). Is there a way to track the status of the copying using shutil.copytree()? Normally with files I would use the code below, but not sure how to do the same with shutil.copytree():

for currentFolder, subFolder, fileNames in os.walk(sourceFolder):
   for i in fileNames:
        if i.endswith(".img"):
            print "copying {}".format(i)
            shutil.copy(os.path.join(currentFolder,i), outPutFolder)

解决方案

Yes, something like this is possible by taking advantage of the function name passed in for 'ignore' parameter. In fact something like this is given in the example section of python docs: https://docs.python.org/2/library/shutil.html#copytree-example

Example pasted below as well:

from shutil import copytree
import logging

def _logpath(path, names):
    logging.info('Working in %s' % path)
    return []   # nothing will be ignored

copytree(source, destination, ignore=_logpath)
