Well, that's the trouble.  You haven't stated your intent, so we're 
forced to try to reverse engineer it. Below I state what my 
reverse-engineering effort thinks is your intent.  It would be better if 
you actually said clearly what you want to achieve.

As best as I can understand what you are trying to do here, it seems 
like you want to enable/disable those Entry widgets when you configure 
the b widget to be enabled/disabled.  That way their states would all 
track each other, with only a single command needing to be issued.

That seems like a sensible goal. The function config_b_and_entries() 
that I suggested is not meant to be the target of a lambda expression 
that is the argument of b.config().  It is meant to be called *instead* 
of b.config(command = lambda.....).  I can't see any benefit of trying 
to force this coordination of states by using an obscure lambda 
expression when you can achieve the same result with a straightforward, 
easy to read function or method call.

OTOH, if you are not trying to achieve this coordination of states, then 
what are you trying to do?  Don't go making us guess any more.
