Shutil - DS_store文件阻止移动的问题

Question

我是一名新的Python开发者，试图编写我的第一个脚本。目标是编写一个应用程序，根据文件类型将文件放入子文件夹中，以清理我的下载文件夹。

这是我的代码：

import shutil
import os

directory = "/Users/Gustaf/downloads"
file_type_list = []
for filename in os.listdir("/Users/Gustaf/downloads"): #insert your downloads folder path
    path = directory
    file_type = os.path.splitext(filename)[1]
    if file_type not in file_type_list:
        file_type_list.append(file_type)
    if file_type in file_type_list:
        continue
    try:
        print(directory + file_type.replace(".", "/"))
        os.mkdir(directory + file_type.replace(".", "/"))
    except OSError as error:
        print(error)

for filename in os.listdir("/Users/Gustaf/downloads"):
    movable_file_path = directory + "/" + "%s" % (filename)
    file_type = os.path.splitext(filename)[1]
    file_type_no_extension = file_type.replace(".", "")
    file_no_extension = os.path.splitext(filename)[0] #used for the full file path in shutil.move
    fileDestination = directory + "/" + "%s" % (file_type_no_extension)

    if os.path.isdir(movable_file_path) == True:
        #skip directories
        print(movable_file_path)
        print("THIS IS A FOLDER" + "\n")
    
    if os.path.isfile(movable_file_path) == True:
        #The files you actually want to move
        print(filename)
        print("THIS IS A FILE" + "\n")
        shutil.move(movable_file_path, fileDestination) 

第一部分可以运行，程序为每种文件类型创建了文件夹，但是当我尝试移动文件时出现以下情况：

Traceback (most recent call last):
  File "/Users/Gustaf/Desktop/Programming/downloads_sorter/main.py", line 41, in <module>
    shutil.move(movable_file_path, fileDestination) 
  File "/usr/local/Cellar/python@3.8/3.8.5/Frameworks/Python.framework/Versions/3.8/lib/python3.8/shutil.py", line 786, in move
    raise Error("Destination path '%s' already exists" % real_dst)
shutil.Error: Destination path '/Users/Gustaf/downloads/.DS_Store' already exists

filename，movable_file_path和fileDestination的输出如下：

DS_Store
/Users/Gustaf/downloads/DS_Store
/Users/Gustaf/downloads/

/Users/Gustaf/downloads/epub

首先出现问题的是DS_Store文件。有些文件可以移动，但遇到这个问题后就无法继续操作。我做错了什么吗？

Answer 1

以下是需要翻译的内容：

• 文件名： DS_Store
• 可移动文件路径：/Users/Gustaf/downloads/DS_Store
• 目标路径：/Users/Gustaf/downloads/

你的代码正在尝试将/Users/Gustaf/downloads/DS_Store中的DS_Store移动到/Users/Gustaf/downloads/DS_Store，这实际上是同一个位置。你根本没有尝试移动DS_Store，所以应该忽略它。你可以通过检查movable_file_path中是否存在fileName来实现这一点。

在这种情况下，你只需修改if语句如下：

if os.path.isfile(movable_file_path) and filename not in movable_file_path:
    #The files you actually want to move
    print(filename)
    print("THIS IS A FILE" + "\n")
    shutil.move(movable_file_path, fileDestination)
