68. File Operations

1. Introduction​

File operations are core to any file manager.
We’ll implement read, write, delete, copy, and move.

2. Reading a File​

def read_file(path):
    try:
        with open(path, "r") as f:
            print(f.read())
    except FileNotFoundError:
        print("File not found")

3. Writing to a File​

def write_file(path, content):
    with open(path, "w") as f:
        f.write(content)
    print("File written successfully")

4. Deleting a File​

import os

def delete_file(path):
    try:
        os.remove(path)
        print("File deleted")
    except FileNotFoundError:
        print("File not found")

5. Copying and Moving Files​

import shutil

def copy_file(src, dst):
    shutil.copy(src, dst)
    print("File copied")

def move_file(src, dst):
    shutil.move(src, dst)
    print("File moved")

6. Integrating with CLI​

if args.command == "read":
    read_file(args.path)
elif args.command == "write":
    write_file(args.path, "Hello World")
elif args.command == "delete":
    delete_file(args.path)

7. Next Steps​

✅ File operations are implemented.
Next: Directory operations (create, list, navigate).
