This finds the right bar, but not its list

Use enumerate() (new in Python 2.3, IIRC). Otherwise:
for i in range(len(sequence)):
item = sequence[i]

Not sure if this is what you are looking for but...
li = ['this','is','a','list','of','strings']
li = [l for l in li if li.index(l) = li.index('a')]
li
['a', 'list', 'of', 'strings']
