HomeBackend DevelopmentPython Tutorialpython实现删除文件与目录的方法

本文实例讲述了python实现删除文件与目录的方法。分享给大家供大家参考。具体实现方法如下:

os.remove(path)
删除文件 path. 如果path是一个目录, 抛出 OSError错误。如果要删除目录,请使用rmdir().

remove() 同 unlink() 的功能是一样的
在Windows系统中,删除一个正在使用的文件,将抛出异常。在Unix中,目录表中的记录被删除,但文件的存储还在。

os.removedirs(path)
递归地删除目录。类似于rmdir(), 如果子目录被成功删除, removedirs() 将会删除父目录;但子目录没有成功删除,将抛出错误。

举个例子, os.removedirs(“foo/bar/baz”) 将首先删除 “foo/bar/ba”目录,然后再删除foo/bar 和 foo, 如果他们是空的话
如果子目录不能成功删除,将 抛出 OSError异常

os.rmdir(path)
删除目录 path,要求path必须是个空目录,否则抛出OSError错误
 
递归删除目录和文件(类似DOS命令DeleteTree):

复制代码 代码如下:
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:

复制代码 代码如下:
import shutil
shutil.rmtree()
一行搞定:
复制代码 代码如下:
__import__('shutil').rmtree()

希望本文所述对大家的Python程序设计有所帮助。
