extract tuple items from list without accessing index

I am trying to extract the tuple items which consist of another embedded tuple without using the index.

items = [(('a', 'b'), 'a'), (('a', 'b'), 'b'), (('a', 'b'), 'c'), (('a', 'b'), 'd')]

# Currently accessing using index
for xy,z in items:
    print(xy[0],xy[1],z)

# Trying without index but getting error
for x, y, z in items:
    print(x,y,z)

for item in items:
    x, y, z = item
    print(x,y,z)

Error:

ValueError: not enough values to unpack (expected 3, got 2)

Is it possible?

>Solution :

Yes, you just need to wrap the nested tuple to have an extra layer of unpacking:

for (x, y), z in items:
    print(x,y,z)

Note how (x, y) causes the inner tuple to be unpacked.
