Process CPU Info

Description​

The process_cpuinfo function processes the command line arguments to extract a device name. By default, it uses "0000000000000000" as the device name if no argument is provided. The function accepts the -m option to specify the device name.

Function Signature:​

def process_cpuinfo() -> str:

Parameters​

This function does not take any parameters. It reads from the command line arguments directly.

Returns​

  • str: The device name. If no -m argument is passed, it returns the default device name "0000000000000000". Otherwise, it returns the device name specified via the -m argument.

Example Usage​

Here’s an example of how the function works:

Without specifying a device name:​

python your_script.py

Output:

0000000000000000

With specifying a device name:​

python your_script.py -m "device123"

Output:

device123

Code​

import getopt
import sys

def process_cpuinfo() -> str:
    device_name = "0000000000000000"

    try:
        optlist, args = getopt.getopt(sys.argv[1:], 'm:')
    except getopt.GetoptError as err:
        # Print help information and exit:
        print(str(err))    # This will print something like "option -a not recognized"
        return device_name

    for option, argument in optlist:
        if option == "-m":
            device_name = argument
                              
    return device_name

Errors and Exceptions​

  • If the function encounters an invalid option (i.e., one not recognized by getopt), it will print an error message and return the default device name "0000000000000000".

Example Error:​

python your_script.py -x

Output:

unknown option -x
0000000000000000

Notes​

  • This function is typically used in scripts where you need to pass a device name via the command line. The function allows the user to specify the device name with the -m option.
  • If the user does not provide the -m option, the default device name is used.
  • This function could be used to process device identifiers passed through command-line arguments for device management, monitoring, or logging purposes.
