Sort last

@anbu23 and @DeaD_EyE thanks for your replies.
Here's the code if anyone needs it in the future :

def sort_last(tuples):
     for t in tuples :
          last_element = t[-1]
     return sorted(tup, key=lambda x:x[-1])
tup =[ (1, 7), (1, 3), (3, 4, 5), (2, 2)]
print(sort_last(tup))

And output :

Output:
[(2, 2), (1, 3), (3, 4, 5), (1, 7)]
