| 61 | Names for built-in exceptions and functions and a number of constants are |
| 62 | found in a separate |
| 63 | symbol table. This table is searched last when the interpreter looks |
| 64 | up the meaning of a name, so local and global |
| 65 | user-defined names can override built-in names. Built-in types are |
| 66 | described together here for easy reference.<A NAME="tex2html1" |

| 70 | The tables in this chapter document the priorities of operators by |
| 71 | listing them in order of ascending priority (within a table) and |
| 72 | grouping operators that have the same priority in the same box. |
| 73 | Binary operators of the same priority group from left to right. |
| 74 | (Unary operators group from right to left, but there you have no real |
| 75 | choice.) See chapter 5 of the <em class="citetitle"><a |
| 76 | href="../ref/ref.html" |
| 77 | title="Python |
| 78 | Reference Manual" |
| 79 | >Python |

| 86 | Most descriptions sorely lack explanations of the exceptions |
| 87 | that may be raised -- this will be fixed in a future version of |
