    15 Names for built-in exceptions and functions and a number of constants are found

    16 in a separate  symbol table.  This table is searched last when the interpreter

    17 looks up the meaning of a name, so local and global user-defined names can

    18 override built-in names.  Built-in types are described together here for easy

    19 reference.

    21 The tables in this chapter document the priorities of operators by listing them

    22 in order of ascending priority (within a table) and grouping operators that have

    23 the same priority in the same box. Binary operators of the same priority group

    24 from left to right. (Unary operators group from right to left, but there you

    25 have no real choice.)  See :ref:`operator-summary` for the complete picture on

    26 operator priorities.
