Firstly, make sure that you run your script as Administrator as Diskpart requires administrative privileges.

The following should return Driveletter R -

try:
        result = subprocess.check_output(cmd, shell=True, stderr=subprocess.STDOUT)
    except subprocess.CalledProcessError as e:
        raise Exception(f"Failed to get drive letter: {e.output.decode('utf-8')}")

    result = result.decode('utf-8')
    for line in result.split('\n'):
        if volume_name in line:
            return line.split()[1]

    raise Exception(f"Failed to get drive letter: Volume '{volume_name}' not found")
    

//An example to get the drive letter of a volume named 'MyDisk'
try:
    drive_letter = get_drive_letter('MyDisk')
    print(f"Drive letter: {drive_letter}")
except Exception as e:
    print(f"Error: {e}")

Solution 2

This should work:

Python

if line.startswith('  Volume '):
    get_drive_letter = line.split()[2]
