Add Variables to Tuple

You can start with a blank tuple with something like t = (). You can add with +, but you have to add another tuple. If you want to add a single element, make it a singleton: t = t + (element,). You can add a tuple of multiple elements with or without that trailing comma.

>>> t = ()
>>> t = t + (1,)
>>> t
(1,)
>>> t = t + (2,)
>>> t
(1, 2)
>>> t = t + (3, 4, 5)
>>> t
(1, 2, 3, 4, 5)
>>> t = t + (6, 7, 8,)
>>> t
(1, 2, 3, 4, 5, 6, 7, 8)

Tuples are immutable; you can't change which variables they contain after construction. However, you can concatenate or slice them to form new tuples:

a = (1, 2, 3)
b = a + (4, 5, 6)  # (1, 2, 3, 4, 5, 6)
c = b[1:]  # (2, 3, 4, 5, 6)

And, of course, build them from existing values:

name = "Joe"
age = 40
location = "New York"
joe = (name, age, location)
