I can't wait for the 

intX_asString_asBool = intX_asString.__bool__()

if (intX_asString_asBool == True):
  # do something

As serious a character as I am, I had good laughs at this. Don't you all 
like my questions for all the exitainment they offer?

The "__str__" issue was a genuine question. I'm glad to find there is also a 
__bool_ () method, shall I need it. :-) Please note, this is not how I write 
my code. I'm not that bad a programmer, it's just Python which is so 
different that I am doing what I need to help clarify things and help me 
out.

I don't find this post offensive, even though JM is deliberately making fun 
of me. But to his credit, it is funny indeed. Let's laugh 2gether!

This reminds me, when I first started working with databases and saw an 
error msg which said that my query had "ambiguous columns" I laughed for 1/2 
hr. I found it incredibly exitaining that a 100% deterministic piece of 
hardware could have the word "ambiguous" in its internal dictionary.

:-))

Enjoy your laugh (laughter's good!), but there are a couple of wrong
assumptions here. The hardware doesn't use the word "ambiguous", and
the SQL engine (which is what does) isn't 100% deterministic. Or to be
more technically correct, it's 100% deterministic with such a large
set of inputs (many of which are outside your access, let alone
control) that it may as well have a random component.  Also, there's
nothing strange about ambiguity: "Go and get the cornflour and the
icing sugar. Put some of it into the cake mix." - what should you put
in? Some of each? That's what the database has been asked to do, and
it's not clear what should be done.

Sorry to be the wet blanket on your joke (I think that metaphor's as
mixed as cake batter), but facts is facts :)
