python - Shutil - DS_store 文件阻塞移动问题

Question

尝试处理我的第一个脚本的新 Python 开发人员。目标是编写一个应用程序，通过根据文件类型将文件放入子文件夹来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) 

第一部分有效，程序为每种文件类型创建文件夹，但是当我尝试移动文件时，我得到了这个:

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

第一个是导致问题的 (DS_store)。有些文件能够移动，但遇到这个后我无处可去。我做错了什么？

Answer 1

对于以下内容:

• 文件名:DS_Store
• 可移动文件路径:/Users/Gustaf/downloads/DS_Store
• 目的地:/Users/Gustaf/downloads/

您的代码所做的是尝试将 DS_Store 从/Users/Gustaf/downloads/DS_Store 到 /Users/Gustaf/downloads/DS_Store 这实际上是同一个地方。您根本没有尝试移动 DS_Store，因此应该忽略它。您可以通过检查 movable_file_path

中是否存在 fileName 来执行此操作

在这种情况下，您可以按如下方式更改 if 语句:

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)
