Python删除目录下所有文件

在开发过程中，经常需要清空某个目录下的所有文件，以便进行新的操作。Python提供了多种方法来实现这一操作，本文将介绍几种常用的方法，并给出相应的示例代码。

方法一：使用os模块和os.path模块

这是最常见的一种方法，通过遍历目录下的所有文件，然后使用os模块的remove函数来删除文件。示例代码如下：

import os

def delete_files_in_dir(dir):
    for file in os.listdir(dir):
        file_path = os.path.join(dir, file)
        if os.path.isfile(file_path):
            os.remove(file_path)
            print(f"{file_path} has been deleted")

# 删除目录下所有文件
delete_files_in_dir("path/to/your/directory")

运行结果示例:

/path/to/your/directory/file1.txt has been deleted
/path/to/your/directory/file2.txt has been deleted
/path/to/your/directory/file3.txt has been deleted
...

方法二：使用shutil模块

shutil模块是Python的一个文件操作模块，提供了更多的文件操作功能，可以更方便地删除目录下的文件。示例代码如下：

import shutil

def delete_files_in_dir(dir):
    for file in os.listdir(dir):
        file_path = os.path.join(dir, file)
        if os.path.isfile(file_path):
            os.remove(file_path)
            print(f"{file_path} has been deleted")

# 删除目录下所有文件
delete_files_in_dir("path/to/your/directory")

运行结果示例:

/path/to/your/directory/file1.txt has been deleted
/path/to/your/directory/file2.txt has been deleted
/path/to/your/directory/file3.txt has been deleted
...

方法三：使用glob模块

glob模块可以通过文件路径的通配符匹配来获取目录下的所有文件，然后删除这些文件。示例代码如下：

import glob

def delete_files_in_dir(dir):
    files = glob.glob(dir + "/*")
    for file in files:
        if os.path.isfile(file):
            os.remove(file)
            print(f"{file} has been deleted")

# 删除目录下所有文件
delete_files_in_dir("path/to/your/directory")

运行结果示例:

/path/to/your/directory/file1.txt has been deleted
/path/to/your/directory/file2.txt has been deleted
/path/to/your/directory/file3.txt has been deleted
...
