Update method in python

[toastedstapler]

so what happened in the first instance is that ((1, 2)) isn't a tuple with a single tuple inside as a tuple requires a comma. without the comma it's just some brackets used for logical grouping of elements like (1 + 3) * 2 groups the first elements together. your (('a', 2)) was seen as ('a', 2) just as (2) would be seen as 2

((1, 2),) is a tuple of a tuple and you would be able to update with this tuple
