okay, now note that you do not actually use the ingroup list for
anything else but getting and setting its first element. So why would
one really need it be a list? Let's replace it with a variable called
ingroup that is not a list anymore. See it below (run it to see what
happens):
----------------------
def blocks(s, start, end):
ingroup = 0
def classify(c):
klass = c==start and 2 or c==end and 3 or ingroup
ingroup = klass==1 or klass==2
return klass
return [tuple(g) for k, g in groupby(s, classify) if k == 1]
print blocks('the {quick} brown {fox} jumped', start='{', end='}')
