add a tuple to a tuple in Python

Question

I have a tuple:

a = (1,2,3)

and I need to add a tuple at the end

b = (4,5)

The result should be:

(1,2,3,(4,5))

Even if I wrap b in extra parents: a + (b), I get (1,2,3,4,5) which is not what I wanted.

Answer 1

When you do a + b you are simply concatenating both the tuples. Here, you want the entire tuple to be a part of another tuple. So, we wrap that inside another tuple.

a, b = (1, 2, 3), (4,5)
print a + (b,)  # (1, 2, 3, (4, 5))
