Given there is no ! operator in Python, I next tried ~ (despite that I'm after a logical not). This came as a surprise:
>>> bool(~True)
True
>>> bool(~False)
True
>>> bool(~~False)
False
>>> ~True, ~~True, ~False, ~~False
(-2, 1, -1, 0)
Is there any consideration to "fixing" this? Is int(True) 1 due to C? Why is it preferred over -1?
It seems more appropriate to me that True have:
def __invert__(self): return False
def __int__(self): return 1 # or even -1
This also "fixes" this case too:
>>> -True
-1 |
