python创建和删除目录的方法

yipeiwu_com6年前Python基础

本文实例讲述了python创建和删除目录的方法。分享给大家供大家参考。具体分析如下:

下面的代码可以先创建一个目录,然后调用自定义的deleteDir函数删除整个目录

#--------------------------------------
#      Name: create_directory.py
#     Author: Kevin Harris
# Last Modified: 02/13/04
#  Description: This Python script demonstrates
#         how to create a single
#         new directory as well as delete a directory
#         and everything 
#         it contains. The script will fail 
#         if encountewrs a read-only
#         file
#--------------------------------------
import os
#--------------------------------------
# Name: deleteDir()
# Desc: Deletes a directory and its content recursively.
#--------------------------------------
def deleteDir( dir ):
  for name in os.listdir( dir ):
    file = dir + "/" + name
    if not os.path.isfile( file ) and os.path.isdir( file ):
      deleteDir( file ) # It's another directory - recurse in to it...
    else:
      os.remove( file ) # It's a file - remove it...
  os.rmdir( dir )
#--------------------------------------
# Script entry point...
#--------------------------------------
# Creating a new directory is easy...
os.mkdir( "test_dir" )
# Pause for a moment so we can actually see the directory get created.
input( 'A directory called "tes_dir" was created.\n\nPress Enter to delete it.' )
# Deleting it can be a little harder since it may contain files, so we'll need 
# to write a function to help us out here.
deleteDir( "test_dir" );

希望本文所述对大家的Python程序设计有所帮助。
