This precise mindset is why the world has suffered for decades (wrt security/integrity/availability) at the hands of what can only be described as an industry led by completely unjustified male confidence. Why are there still people fighting the “it’s not that bad, guys! you’ve just got to be a good developer like ME!” fight?

Is None OK in Python?

NULL in C just doesn’t belong at the end of a string. But IMO having a “there is no value here” designation is not a bad thing.

I think you're mixing up the NULL pointer and the NULL (sometimes NUL) character.
