[Tutor] Question on re.findall usage

[Dave Wilder]

Hello,

I am trying using re.findall to parse the string below and then create a list from the results.
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'

What I am doing now is obviously quite ugly, but I have not yet able to manipulate it to work how I want but in a much more efficient and modular way.
I did some research on re.findall but am still confused as to how to do character repetition searches, which  I guess is what I need to do here.
>> junk_list = re.findall(r'(auto|[1|4]0+[A-Z]-[HF]D|[1|4]0+[A-Z][A-Z]-[HF]D|[1|4]0+[A-Z][A-Z][0-9])', junk_list)
>> junk_list
['auto', '40000SR4', '10T-HD', '100TX-FD', '100TX-HD', '40000LR4', '1000T-FD', '1000T-HD']
>>>

Basically, all I need to search on is:
-       auto
-       anything that starts w/ '1' or '4' and then any number of subsequent zeroes   e.g. 10T-HD, 40000LR4-FD, 100TX-FD

My environment:
[root at f5ite ~/tests]$ uname -a
Linux VM-QA-ITE-03 2.6.32-220.17.1.el6.i686 #1 SMP Tue May 15 22:09:39 BST 2012 i686 i686 i386 GNU/Linux

Type "help", "copyright", "credits" or "license" for more information.

Any ideas?

Thanks,

Dave
