Access file in external hard drive using python on mac

When working with Python on a Mac, accessing files on an external hard drive can sometimes be a challenge. However, there are several ways to solve this problem. In this article, we will explore three different options to access files on an external hard drive using Python on a Mac.

Option 1: Using the os module

The os module in Python provides a way to interact with the operating system. We can use the os module to navigate through the file system and access files on an external hard drive. Here’s an example:

import os

external_drive_path = "/Volumes/ExternalDrive"
file_path = os.path.join(external_drive_path, "file.txt")

with open(file_path, "r") as file:
    content = file.read()

print(content)

In this example, we first specify the path to the external hard drive using the external_drive_path variable. Then, we use the os.path.join() function to create the complete file path by combining the external drive path and the file name. Finally, we open the file using the open() function and read its content.

Option 2: Using the pathlib module

The pathlib module in Python provides an object-oriented approach to working with file paths. We can use the pathlib module to access files on an external hard drive. Here’s an example:

from pathlib import Path

external_drive_path = Path("/Volumes/ExternalDrive")
file_path = external_drive_path / "file.txt"

with open(file_path, "r") as file:
    content = file.read()

print(content)

In this example, we create a Path object using the external drive path. Then, we use the / operator to join the external drive path and the file name. Finally, we open the file and read its content.

Option 3: Using the shutil module

The shutil module in Python provides a higher-level interface for file operations. We can use the shutil module to copy files from an external hard drive to the local machine and then access them. Here’s an example:

import shutil

external_drive_path = "/Volumes/ExternalDrive/file.txt"
local_file_path = "/Users/Username/Desktop/file.txt"

shutil.copy(external_drive_path, local_file_path)

with open(local_file_path, "r") as file:
    content = file.read()

print(content)

In this example, we specify the path to the file on the external hard drive using the external_drive_path variable. Then, we specify the path to the local machine where we want to copy the file using the local_file_path variable. We use the shutil.copy() function to copy the file from the external hard drive to the local machine. Finally, we open the local file and read its content.

After exploring these three options, it is clear that using the pathlib module provides a more elegant and object-oriented approach to accessing files on an external hard drive using Python on a Mac. The pathlib module simplifies the process of working with file paths and offers a more intuitive syntax. Therefore, option 2 is the recommended solution.

    1. Sorry, but I have to disagree. Option 1 is the way to go. Its tried, tested, and reliable. No need to complicate things with pathlib. Stick with what works.
