[Tutor] RE: __and__

[Arne Mueller]

Hi All,

the manual is a bit confusing, in section 3.5 ( operator -- Standard
operators as functions.) it says:

and_ (a, b) 
__and__ (in operator) (a, b) 
    Return the bitwise and of a and b. 

the same as 

add (a, b) 
__add__ (in operator) (a, b) 
    Return a + b, for a and b numbers. 

So I thought __and__ it'd work the same way as __add__ ... :-(
