Not sure if you were looking for a method that retained the existing
nested structure or not, so the following is a recursive way of
turning an arbitrarily nested tuple structure into the list based
equivalent:
a = ((1,2), (3,4), (5,6), (7,(8,9)))
def t2l(a):
lst = []
for item in a:
if type(item) == tuple:
lst.append(t2l(item))
else:
lst.append(item)
return lst
print t2l(a)
