python删除文件

import os

删除文件：

os.remove()

删除空目录：

os.rmdir()

递归删除空目录：

os.removedirs()

递归删除目录和文件（类似DOS命令DeleteTree）：

方法1：自力更生，艰苦创业

# Delete everything reachable from the directory named in 'top',

# assuming there are no symbolic links.

# CAUTION:  This is dangerous!  For example, if top == '/', it

# could delete all your disk files.

import os

for root, dirs, files in os.walk(top, topdown=False):

for name in files:

os.remove(os.path.join(root, name))

for name in dirs:

os.rmdir(os.path.join(root, name))

方法2：前人栽树，后人乘凉

import shutil

shutil.rmtree()

一行搞定 __import__('shutil').rmtree()
