It's not "extra verbiage", you print the whole sg object, and the author of 
the SecurityGroup class has chosen one way to convert SecurityGroup 
instances into strings, the one that he deems most useful, probably for 
debugging purposes.

But you are only interested in some attributes of the sg object. Instead of

print sg

you should only print

print sg.foo, sg.bar

foo and bar are fictitious attribute names, but you can find candiates for 
these attributes with

print dir(sg)

which will print the actual names.
