Python shutil.copytree()用法及代碼示例

Shutil模塊Python提供了許多對文件和文件集合進行高級操作的函數。它屬於Python的標準實用程序模塊。此模塊有助於自動執行文件和目錄的複製和刪除過程。
shutil.copytree()方法以遞歸方式將以源(src)為根的整個目錄樹複製到目標目錄。由(dst)命名的目標目錄必須不存在。它將在複製期間創建。使用copystat()複製目錄的權限和時間,並使用shutil.copy2()複製單個文件。

用法: shutil.copytree(src, dst, symlinks = False, ignore = None, copy_function = copy2, igonre_dangling_symlinks = False)
參數:
src: A string representing the path of the source directory.
dest: A string representing the path of the destination.
symlinks (optional):This parameter accepts True or False, depending on which the metadata of the original links or linked links will be copied to the new tree.
ignore (optional):If ignore is given, it must be a callable that will receive as its arguments the directory being visited by copytree(), and a list of its contents, as returned by os.listdir().
copy_function (optional):The default value of this parameter is copy2. We can use other copy function like copy() for this parameter.
igonre_dangling_symlinks (optional):This parameter value when set to True is used to put a silence on the exception raised if the file pointed by the symlink doesn’t exist.
返回值: This method returns a string which represents the path of newly created directory.

範例1:
使用shutil.copytree()將文件從源複製到目標的方法

# Python program to explain shutil.copytree() method  
       
# importing os module  
import os  
   
# importing shutil module  
import shutil  
   
# path  
path = 'C:/Users / Rajnish / Desktop / GeeksforGeeks'
   
# List files and directories  
# in 'C:/Users / Rajnish / Desktop / GeeksforGeeks'  
print("Before copying file:")  
print(os.listdir(path))  
   
   
# Source path  
src = 'C:/Users / Rajnish / Desktop / GeeksforGeeks / source'
   
# Destination path  
dest = 'C:/Users / Rajnish / Desktop / GeeksforGeeks / destination'
   
# Copy the content of  
# source to destination  
destination = shutil.copytree(src, dest)  
   
# List files and directories  
# in "C:/Users / Rajnish / Desktop / GeeksforGeeks"  
print("After copying file:")  
print(os.listdir(path))  
   
# Print path of newly  
# created file  
print("Destination path:", destination)
輸出:
Before copying file:
['source']
After copying file:
['destination', 'source']
Destination path:C:/Users/Rajnish/Desktop/GeeksforGeeks/destination

範例2:
使用shutil.copytree()使用複製文件的方法shutil.copy()方法。

# Python program to explain shutil.copytree() method  
        
# importing os module  
import os  
    
# importing shutil module  
import shutil  
    
# path  
path = 'C:/Users / Rajnish / Desktop / GeeksforGeeks'
    
# List files and directories  
# in 'C:/Users / Rajnish / Desktop / GeeksforGeeks'  
print("Before copying file:")  
print(os.listdir(path))  
    
    
# Source path  
src = 'C:/Users / Rajnish / Desktop / GeeksforGeeks / source'
    
# Destination path  
dest = 'C:/Users / Rajnish / Desktop / GeeksforGeeks / destination'
    
# Copy the content of  
# source to destination  
# using shutil.copy() as parameter 
destination = shutil.copytree(src, dest, copy_function = shutil.copy)  
    
# List files and directories  
# in "C:/Users / Rajnish / Desktop / GeeksforGeeks"  
print("After copying file:")  
print(os.listdir(path))  
    
# Print path of newly  
# created file  
print("Destination path:", destination)
輸出:
Before copying file:
['source']
After copying file:
['destination', 'source']
Destination path:C:/Users/Rajnish/Desktop/GeeksforGeeks/destination
