Overview

In this tutorial, we will explore the shutil module in Python, which provides a high-level interface for various file operations. The shutil module allows us to perform tasks such as copying, moving, and deleting files and directories, as well as working with archives. By the end of this tutorial, you will have a solid understanding of how to utilize the shutil module for your file manipulation needs.

Before proceeding with this tutorial, it is assumed that you have a basic understanding of Python programming language, including file handling concepts. Furthermore, ensure that you have Python 3 installed on your machine.

Installation

The shutil module comes bundled with Python, so there is no need to install any additional packages. You can import the module directly in your Python script by using the following statement: python import shutil With the shutil module imported, let’s dive into some practical examples to see how it can be used for high-level file operations.

Copying Files

To copy files using the shutil module, we can use the shutil.copy() function. This function takes two parameters: the source file and the destination file.

Here’s an example that demonstrates how to copy a file from one location to another: ```python import shutil

# Copy a file
shutil.copy('source.txt', 'destination.txt')

print('File copied successfully.')
``` In the above example, the `source.txt` file is copied to `destination.txt`. If the destination file already exists, it will be overwritten.

Keep in mind the directory path when specifying the source and destination files. If the files are located in different directories, provide the full path to both files.

Moving and Renaming Files

The shutil module also provides a way to move files from one location to another using the shutil.move() function. Similar to copying files, the move() function requires the source and destination file paths.

Let’s see an example: ```python import shutil

# Move a file
shutil.move('source.txt', 'destination.txt')

print('File moved successfully.')
``` In the above example, the `source.txt` file is moved to `destination.txt`. If the destination file already exists, it will be overwritten.

Additionally, you can use the shutil.move() function to rename files by specifying a different destination file name. ```python import shutil

# Rename a file
shutil.move('old_name.txt', 'new_name.txt')

print('File renamed successfully.')
``` The above code renames the `old_name.txt` file to `new_name.txt`.

Deleting Files and Directories

The shutil module allows us to delete files and directories using the shutil.rmtree() function. This function recursively deletes all files and directories within the specified path.

Here’s an example: ```python import shutil

# Delete a directory and its contents
shutil.rmtree('directory_path')

print('Directory deleted successfully.')
``` In the example above, the `directory_path` directory and all its contents (including files and subdirectories) are deleted.

To delete a single file, you can use the os.remove() function from the os module, which works similarly to shutil.rmtree() but only for files. ```python import os

# Delete a file
os.remove('file.txt')

print('File deleted successfully.')
``` The above code deletes the `file.txt` file from the specified path.

Working with Archives

The shutil module also provides functionality to work with archives such as ZIP files. We can use the shutil.make_archive() function to create a new archive file.

Here’s an example: ```python import shutil

# Create a ZIP archive of a directory
shutil.make_archive('/path/to/archive', 'zip', '/path/to/directory')

print('Archive created successfully.')
``` In the above example, a ZIP archive is created of the `directory` located at `/path/to/directory`. The resulting archive file will be named `archive.zip` and saved in the specified path.

To extract the contents of an archive, we can use the shutil.unpack_archive() function: ```python import shutil

# Extract the contents of a ZIP archive
shutil.unpack_archive('archive.zip', '/path/to/destination')

print('Archive extracted successfully.')
``` The above code extracts the contents of the `archive.zip` file to the `/path/to/destination` directory.

Conclusion

In this tutorial, you have learned about the shutil module in Python, which provides high-level file operations. We explored how to copy, move, and delete files and directories using shutil.copy(), shutil.move(), shutil.rmtree(), and os.remove(). Additionally, we saw how to work with archives by creating and extracting them using shutil.make_archive() and shutil.unpack_archive().

The shutil module is a powerful tool for handling file-related tasks in a convenient and efficient manner. You can now utilize its capabilities to perform various file operations in your Python projects.

Remember to refer to the official Python documentation for more details and advanced usage of the shutil module. Keep practicing and experimenting with different scenarios to enhance your understanding and proficiency with the module. Happy coding!
