python - Regular Expressions Help needed -

if want extract list of ['horror', 'adult', 'cult movies', etc..] class 'pandas.core.index.index, best regex this? grabs following capital ts until closed bracket? bad approach, given "television" starts capital t? should approach here? i've never used regex before appreciate advice/code!

index([u'variable[t.horror]', u'variable[t.adult]', u'variable[t.cult movies]', u'variable[t.mystery & suspense]', u'variable[t.science fiction & fantasy]', u'variable[t.western]', u'variable[t.gay & lesbian]', u'q("tomato-meter")', u'variable[t.comedy]', u'variable[t.television]', u'variable[t.kids & family]', u'variable[t.classics]', u'variable[t.drama]', u'variable[t.art house & international]', u'variable[t.romance]', u'variable[t.special interest]', u'variable[t.animation]', u'variable[t.documentary]', u'variable[t.musical & performing arts]', u'variable[t.sports & fitness]', u'variable[t.faith & spirituality]', u'variable[t.anime & manga]', u'intercept'], dtype='object') 

you can use following regex:

(?<=t\.)([^\]]+)
