how to make a tuple from array

Question

I've a list of values in an array:

 departamentos = ["Piura", "Lima"]

And I would like to transform it to:

 departamentos = (("Piura", "Piura"), ("Lima", "Lima"),)

I've tried this:

for i in departamentos:
     mis_departamentos_b  = mis_departamentos + ((i, i))

But it only returns the last item as a tuple.

mis_departamentos_b
('Lima', 'Lima')

Answer 1

How about

tuple((x,x) for x in departamentos)

---

(('Piura', 'Piura'), ('Lima', 'Lima'))
