Why python does not raise NameError -

consider simple case:

i = 10 if != id:     print 

as id not defined here assuming nameerror: name 'id' not defined not raise any.

but in case:

id = 10 if != id:     print 

it raised nameerror exception i. can explain me behaviour?

id built-in function, defined. use name variable.

here list of built-in functions.
