本文实例讲述了python实现搜索本地文件信息写入文件的方法。分享给大家供大家参考,具体如下:
主要功能:
在指定的盘符,如D盘,搜索出与用户给定后缀名(如:jpg,png)相关的文件,然后把搜索出来的信息(相关文件的绝对路径),存放到用户指定的文件(如果文件不存在,则建立相应的文件)中
先卡看运行效果吧:
运行效果的前部分:
运行效果的后部分:
写入信息后的文件:
代码部分:
#在指定的盘符,如D盘,搜索出与用户给定后缀名(如:jpg,png)相关的文件
#然后把搜索出来的信息(相关文件的绝对路径),存放到用户指定的
#文件(如果文件不存在,则建立相应的文件)中
import os
import time
#指定盘符
DESK = 'E:\'
#信息保存文件的路径
########## 这里请先建立好此文件,我在做文件操作的过程中
########## 使用os.mknod('E:\info.txt'),系统不会建立文件的
SAVE_FILE = 'E:\info.txt'
#文件后缀类型
FILE_EXT = ['bmp','jpeg','gif','psd','png','jpg']
#定义全局变量

#文件个数

#符合要求的文件个数
RIGHT_FILES_NUMBER = 0
#不符合要求的文件个数
NOT_RIGHT_FILES_NUMBER = 0
#文件夹个数

#获取指定文件夹下面的所有文件及文件夹
#如果指定的文件夹不存在,则返回相应的提示信息

#这里是做测试用的,由于扫描整个盘符涉及到的文件和文件夹很多,可能要花一定的时间
