However at the time locals() is called/evaluated, "result" hasn't yet
been created/defined, so I wouldn't expect to see any representation
of "result" in the return value. If it existed before the locals()
call, I would expect to see the value it had before the call:
def test()
a = 1
b = 2
result = "Steven"
result = [value for key, value in locals().items()]
return result
test() # return [1, 2, "Steven"]
