When I need something like this, I usually rop a line on the module
namespace that goes like:
first = lambda x: next(iter(x))
That doesn't meet the requirement that x has ONLY one item.
And using lambda like that is bad style. This would be better:
def first(x): return next(iter(x))
and now first has a proper __name__.
I know that. But then, I'd rather write it as 3-4 lines in some utils module.
So, although I was initially -1 to -0 on this suggestion, maybe it has a point.
Plop this one-liner somewhere: exec('def single(x):\n [v] = x\n return v')
