Some people like to use regexes for everything. I prefer to try string methods first as I find them easier to understand. 
Here's my attempt:
>>> junk_list = 'tmsh list net interface 1.3 media-ca \rpabilities\r\nnet interface 1.3 {\r\n    media-capabilities {\r\n        none\r\n        auto\r\n     40000SR4-FD\r\n  10T-HD\r\n        100TX-FD\r\n        100TX-HD\r\n        1000T-FD\r\n        40000LR4-FD\r\n     1000T-HD\r\n    }\r\n}\r\n'
>>> junk_list = [s.strip() for s in junk_list.splitlines()] junk_list = 
>>> [s for s in junk_list if s == 'auto' or s[:2] in ('10', '40')] 
>>> junk_list
['auto', '40000SR4-FD', '10T-HD', '100TX-FD', '100TX-HD', '1000T-FD', '40000LR4-FD', '1000T-HD']

Does that do what you want?

*****************************

Got it Oscar.  Thank you for your respectful corrections and your solution.
 I used "Rich Text" which is what  I thought was recommended by the list gurus at one point.   Plain Text it is then.

Your response definitely does the trick and I can use that as a base for the future.

As per Joel's comment that it is a variation of questions I asked in the past, right you are.   I had to put this away for a while and am picking it up again now.
I will get string manipulation / RegEx educated.

Thank You,

Dave
