Used in many places |
| This table gives Python’s operator precedence (lowest to highest). |
| From lowest priority (most loosely coupled) to highest priority (most tightly coupled). |
| This means that within an expression, Python will first evaluate operators listed lower in the table, and then evaluate operators listed higher in the table. |
