In the end, I would think that an expression like
In [10]: bool(And(a>2, a<3))
Out[10]: True
should raise a TypeError, like
In [11]: bool(a>2)
[snip]
TypeError: cannot determine truth value of
a > 2
I assume so as, as there is no way to know if a is between 2 and 3.
Shouldn't it have the same behavior as this form of the same condition?
In [12]: a>2 and a<3
[snip]
TypeError: cannot determine truth value of
a > 2
