python对文件目录的操作方法实例总结

2021-07-19 00:05轻舞肥羊 Python

这篇文章主要介绍了python对文件目录的操作方法,结合实例形式总结分析了Python针对文件目录相关的遍历、删除、移动、查找等操作技巧,需要的朋友可以参考下

本文实例讲述了python对文件目录的操作方法。分享给大家供大家参考，具体如下：

python 可以很方便的对文件进行打开，读写操作，删除操作，也可以很方便的对文件夹进行遍历操作。总体说来，有如下几个方面：

1. python 遍历文件目录，当然可以递归
2. python 删除文件
3. python 对文件进行重命名操作
4. python 创建文件夹（多个层级创建）
5. python 删除文件夹（多个层级删除）
6. python 移动文件
7. python 查找文件
8. 得到文件夹的大小

下面的代码是我在用python 做一个网盘服务端的时候用到的一些方法，记录下来，以供以后参考.
