场景：某个文件夹下面包含数量巨大的文件，需求需要将这些文件按组（比如5000个一组）存放到不同的目录中去。

复制代码 代码如下:

# Filename: CopyFiles.py

import os

import os.path

folder_capacity = 20

def copy_files(src_dir, dest_dir):

count = 0

current_folder = ''

for item in os.listdir(src_dir):

abs_item = os.path.join(src_dir, item)

if os.path.isfile(abs_item):

count += 1

if count%folder_capacity == 1:

current_folder = os.path.join(dest_dir, str(count/folder_capacity))

os.mkdir(current_folder)

open(os.path.join(current_folder, item), 'wb').write(open(abs_item, 'rb').read())

copy_files(r'C:src', r'C:dest')
