在Python中复制多文件至另一文件夹，应选用shutil的哪个方法？

Hey there! Let's break down the key differences between those shutil methods so you can pick the perfect one for your file copying task on Windows 10:

Core Differences Between the Methods #

• shutil.copyfileobj(): This is the lowest-level option—you have to manually open source/target file objects first. It's great if you need custom buffering or are working with already-open files, but way overkill for simple "copy from folder A to B" tasks.
• shutil.copyfile(): Only copies the raw file content, no metadata (like creation/modification timestamps, file permissions). Also, the target has to be a full file path (not just a folder), which makes it less flexible for batch copying.
• shutil.copy(): Copies file content plus basic file permissions (read/write access). If you pass a folder as the target, it automatically uses the original filename for the copied file—this is more flexible than copyfile().
• shutil.copy2(): Copies file content and all metadata (timestamps, permissions, etc.). This matches exactly what happens when you right-click a file and select "Copy/Paste" in Windows, making it the most intuitive choice for everyday copying.

Recommendation for Your Task #

For simple batch file copying on Windows 10, shutil.copy2() is the best pick. It preserves all the file metadata you'd expect from a normal system copy, and it handles folder targets seamlessly. If you truly don't care about keeping timestamps or permissions, shutil.copy() works too—but copy2() is almost always the safer, more user-friendly option.

Example Code: Copy Multiple Files #

Here's a quick script to copy all files from a source folder to a target folder using shutil.copy2():

import shutil
import os

# Replace these paths with your actual folders
source_directory = r"C:\Your\Source\Folder"
target_directory = r"C:\Your\Target\Folder"

# Create target folder if it doesn't exist
os.makedirs(target_directory, exist_ok=True)

# Loop through all items in the source folder
for item in os.listdir(source_directory):
    source_path = os.path.join(source_directory, item)
    # Only process files (skip subfolders)
    if os.path.isfile(source_path):
        target_path = os.path.join(target_directory, item)
        shutil.copy2(source_path, target_path)
        print(f"Successfully copied: {item}")
