Well consider this:

str (4) '4' int(str (4)) 4 str (False) 'False'

bool(str(False)) True

Doesn't this seem a bit inconsisent?

The former case is a conversion from an expression that does not have an interpretation in a numerical context to an integer.

The latter case is a canonicalization from an expression that does have an interpretation in a boolean context to the equivalent boolean constant.

I don't have a problem with that. YMMV.
