\chapter{Built-in Objects \label{builtin}} Names for built-in exceptions and functions and a number of constants arefound in a separate symbol table.  This table is searched last when the interpreter looksup the meaning of a name, so local and globaluser-defined names can override built-in names.  Built-in types aredescribed together here for easy reference.\footnote{	Most descriptions sorely lack explanations of the exceptions	that may be raised --- this will be fixed in a future version of	this manual.}\indexii{built-in}{types}\indexii{built-in}{exceptions}\indexii{built-in}{functions}\indexii{built-in}{constants}\index{symbol table} The tables in this chapter document the priorities of operators bylisting them in order of ascending priority (within a table) andgrouping 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 realchoice.)  See chapter 5 of the \citetitle[../ref/ref.html]{PythonReference Manual} for the complete picture on operator priorities.
