python删除文件

Posted 2020-07-26

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()
