python: bug or feature?

Surely you're joking?

The same reason there are different precedence levels for the
arithmetic operators +,-,*,/.  Because that's how everybody
_expects_ things to behave based on years of experience with
other languages and because we were taught math that way even
before we started using computers.

When somebody sees the expression 

            3x+1
            
They expect it to mean (3x) + 1, and not 3(x+1).  So that's
the way operator precedence was defined for programming
languages.

It needs at least three to be consistent with the way boolean
expression are generally used.
