 |  | 
 | Names for built-in exceptions and functions and a number of constants are found | 
 | in a separate  symbol table.  This table is searched last when the interpreter | 
 | looks up the meaning of a name, so local and global user-defined names can | 
 | override built-in names.  Built-in types are described together here for easy | 
 | reference. | 
 |  | 
 | The tables in this chapter document the priorities of operators by listing them | 
 | in order of ascending priority (within a table) and grouping operators that have | 
 | the same priority in the same box. Binary operators of the same priority group | 
 | from left to right. (Unary operators group from right to left, but there you | 
 | have no real choice.)  See :ref:`operator-summary` for the complete picture on | 
 | operator priorities. |
