2 years ago Hi,
Without seeing the whole code I think the issue is you are passing in a byte array ( variable ifconfig_result) This needs to be a string for re.search to work, then when you get the result mac_address_search_result you will need to get the nth index of it to return a string as it is an object still. so to review convert ifconfig_result to string use mac_address_search_result[0] to pass the resulting string of "08:00:27:50:4c:14" in your above example
Hope this helps resolve your issue, if it does resolve your issue please mark this issue as resolved
can you help, where i made a mistake.
