All right, so what you meant was "Assuming that arg is a list, 'if arg==True' will always fail because lists never compare equal to any boolean." > Actually, it's this statement that's non-sensical. > > <quote> > "if arg==True" tests whether the object known as arg is equal to the > object known as True. > </quote> > > [snip examples of "surprising" equality tests...] The statement I made is simply the meaning of "if arg==True" by definition, so I don't see how it can be nonsensical. The problem is that you consider equality tests in Python to be nonsensical because they don't fit with your opinion of what equality should mean.
