Python重命名和删除文件「python 重命名文件」

Python重命名和删除文件的实现方法

在计算机编程中，文件操作是常见的需求之一，Python作为一种强大的编程语言，提供了丰富的文件操作功能，包括文件的创建、读取、写入、重命名和删除等，本文将详细介绍如何使用Python实现文件的重命名和删除操作。

一、文件重命名

1. 使用os模块的rename()函数

os模块是Python的标准库之一，提供了丰富的操作系统相关的功能，os.rename()函数可以实现文件的重命名操作，其语法如下：

os.rename(src, dst)

参数说明：

- src：源文件路径，即需要重命名的文件；

- dst：目标文件路径，即重命名后的文件路径。

示例代码：

import os

src = "old_file.txt"
dst = "new_file.txt"

os.rename(src, dst)

2. 使用shutil模块的move()函数

shutil模块也是Python的标准库之一，提供了高级的文件操作功能，shutil.move()函数可以实现文件的移动（实际上是重命名）操作，其语法如下：

shutil.move(src, dst)

import shutil

src = "old_file.txt"
dst = "new_file.txt"

shutil.move(src, dst)

二、文件删除

1. 使用os模块的remove()函数

os模块中的os.remove()函数可以实现文件的删除操作，其语法如下：

os.remove(path)

- path：需要删除的文件路径。

import os

file_path = "file_to_delete.txt"
os.remove(file_path)

2. 使用os模块的unlink()函数

os模块中的os.unlink()函数也可以实现文件的删除操作，其语法与os.remove()函数相同，需要注意的是，os.unlink()函数只能删除空文件或目录，如果需要删除非空文件或目录，请使用shutil模块的rmtree()函数。

```python

import os

import shutil

import tempfile

import os.path as op
