okey first the expression eval:

( name and month and year ) = ( name=True and month=True and year=True )

then if '=' not in (name = True and month = True and year = True)

I still do not follow how this works. it just doesn't make any sense to 
me at all.


if '=' not in ( name and month and year ):
if '=' not in ( name or month or year ):

I try to read both of them them as an English sentence but i cannot.
how can you be able to understand this?
