Using re.search in Python

Question

search so that I can extract the mac address of my device from a list of strings. I need to match this device name:

Device 5: Broadcom Bluetooth Device (APPLE - 00:02:72:C7:EB:AC)

and I want to extract the bdaddress in the end, that is, (00:02:72:C7:EB:AC).

How can I do that?

>>> import re
>>> pattern = re.compile(r'\(.* - (.*)\)')

This looks for anything in the format (<characters><space><hyphen><space><string>). Since we are interested in the we enclose that in parentheses to mark it as a group.

>>> string = 'Device 5: Broadcom Bluetooth Device (APPLE - 00:02:72:C7:EB:AC)'
>>> matches = re.search(pattern, string)

When you do a re.search on it it results in two groups:

group 0 - (APPLE - 00:02:72:C7:EB:AC)
group 1 - 00:02:72:C7:EB:AC

We are interested in group 1, so we access it as:

>>> matches.group(1)
'00:02:72:C7:EB:AC'
