[Tutor] Iterate Through a Dictionary where the Values are Tuples

[Christopher Gass]

Hello,
I'm working on a project to write a script that will do some basic unit
recommendations for a fire department while their usual computer system is
offline. Right now it's a proof of concept, so it's not built out fully. As
part of this script, I'm attempting to iterate over a dictionary where the
values are tuples. More specifically, the keys are the unit numbers for the
fire apparatus and the values are a tuple containing the unit type (Engine,
Aid Car, etc.) and assigned station. I'm calling the tuple containing the
unit type and station assignment "details" and I'm trying to then iterate
through that tuple to see if the unit type and station assignment match
what's being requested in the response plan. When I try to
iterate through "details" however, I'm receiving a "too many values to
unpack" error. Do you have a solution to this error or maybe another way I
could approach the problem? Thanks for the help.

and unit not in result:
                            result.append(unit)
                            apparatus.append(response_plan[i])
                            i += 1
