I'm new to using Spyder 2.3.0 and Python 3.4.1

I have a directory structure with sub directories.

Unlike other examples on the web I want to select multiple file types and copy the directory structure across. I have tried below and it works but it takes only one file type at a time and “<code>copytree’s” across (it’s going to be very slow).

Is there a way or different way to streamline this to make it faster?

What I was thinking I wanted to do was:

Make a comprehensive list of file types and locations (walking through directory structure)

For example ending with 

fileExt = [".txt", ".doc", ".docx", ".xls",".xlsx", ".ppt", ".pptx", ".m", ".xmcd", ".pdf " ]

Then with that list simply “<code>shutil.copytree”</p>

Any advice greatly appreciated.

  srcDir  = 'c:/a/src/dir/'
  dirName = 'c:/a/dest/dir/'


import os
import shutil

dstDir = os.path.abspath(dirName)

def ignore_list(path, files):

    filesToIgnore = []

    for fileName in files:

        fullFileName = os.path.join(os.path.normpath(path), fileName)

        if not os.path.isdir(fullFileName) and not fileName.endswith('.txt') :

            filesToIgnore.append(fileName)

    return filesToIgnore

# start of script

shutil.copytree(srcDir, dstDir, ignore=ignore_list)

    filesToIgnore = []

        fullFileName = os.path.join(os.path.normpath(path), fileName)

        if not os.path.isdir(fullFileName) and not fileName.endswith('.docx') :


            filesToIgnore.append(fileName)

    return filesToIgnore

shutil.copytree(srcDir, dstDir, ignore=ignore_list)

Copy and paste changing “endswith('.docx') :”</p>

这行得通，我知道它不漂亮，但它行得通

srcDir  = 'c:/a/src/dir/
dstDir = 'c:/a/dest/dir/'


A01= '.doc'
A02= '.docx'
A03= '.xls'
A04= '.xlsx'
A05= '.ppt'
A06= '.pptx'
A07= '.m'
A08= '.xmcd'
A09= '.inp'
A10= '.pdf'
A11= '.DOC'
A12= '.DOCX'
A13= '.XLS'
A14= '.XLSX'
A15= '.PPT'
A16= '.PPTX'
A17= '.M'
A18= '.XMCD'
A19= '.INP'
A20= '.PDF'

    return filesToIgnore




shutil.copytree(srcDir, dstDir, ignore=ignore_list)

我们可以多执行你的“ignore_list”方法

valid_formats = ["txt", "doc", "docx", "xls","xlsx", "ppt", "pptx", "m", "xmcd", "pdf "]

import timeit
import os.path as op

def ignore_list(path, files):
    dag_path = [op.join(op.normpath(path), f) for f in files]
    return [ff for ff in dag_path if not op.isdir(ff) and ff.split(".")[-1] not in valid_formats]

start = timeit.default_timer()
ignore = ignore_list(path, files)
print ("Time: {0}".format(str(timeit.default_timer()-start)))
