How to Copy Files in Python

Copying files in Python can be achieved using the built-in shutil module, which provides a high-level interface for file operations. The shutil.copy() function allows you to copy a file from a source location to a destination location. Here is a simple example demonstrating how to use the shutil.copy() function:

import shutil

source = 'path/to/source/file.txt'
destination = 'path/to/destination/file.txt'

shutil.copy(source, destination)

print("File copied successfully!")

In the code snippet above, we import the shutil module and specify the paths for the source file and the destination file. We then call the shutil.copy() function with the source and destination paths as arguments to copy the file. a success message is displayed once the file is copied.

Handling File Overwrite in Python

When copying files, it is essential to consider scenarios where the destination file already exists. By default, the shutil.copy() function will raise a FileExistsError if the destination file exists. To handle this situation, you can use the shutil.copy2() function, which preserves the original file metadata. Here is an example demonstrating how to handle file overwrite:

import shutil

source = 'path/to/source/file.txt'
destination = 'path/to/destination/file.txt'

try:
    shutil.copy2(source, destination)
    print("File copied successfully!")
except shutil.SameFileError:
    print("Source and destination are the same file")
except IsADirectoryError:
    print("Destination is a directory")
except PermissionError:
    print("Permission denied")

In the code above, we use a try-except block to catch specific exceptions that may occur during the file copying process. By using shutil.copy2(), we ensure that the original file metadata is retained while handling potential errors gracefully.

Recursive File Copy in Python

In some cases, you may need to copy entire directories and their contents recursively. The shutil.copytree() function allows you to copy directories and their files recursively. Here is an example demonstrating how to copy a directory recursively:

import shutil

source_dir = 'path/to/source/directory'
destination_dir = 'path/to/destination/directory'

shutil.copytree(source_dir, destination_dir)

print("Directory copied successfully!")

By using shutil.copytree(), you can efficiently copy directories along with their contents to a specified destination.

Mastering file operations in Python, such as copying files, is essential for handling data manipulation tasks effectively. By leveraging the built-in shutil module, you can perform file copy operations with ease and handle various scenarios that may arise during the process.
