# 4. Built-in Objects

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 Summary for the complete picture on operator priorities.
