But why will a tuple with two elements will always evaluate to
True?
Thats the rule for evaluationg collections in Python.
An empty collection is False. Anything else is therefore true
if []: -> false
if [1,2]: -> true
if (): -> false
if (1,2) - True
if "": -> False
if "foo": -> True
Does that help?
