Hello Dear Students
In this post, I am sharing important python expression evaluation question answers with valid reasons. These questions help you to understand the precedence of operators in python.
All the best.
Operator Precedence in Python
Operator Precedence :
Execution of the operator depends on the precedence of the operator.
| Order | Operator | Description |
| Highest | () | Parentheses |
| ↑ | ** | Exponentiation (right to left) |
| | | ~ | Bitwise nor |
| | | +, – | Unary plus and Minus |
| | | *, /, //, % | Multiplication, Division, floor division, remainder |
| | | +, – | Addition, Subtraction |
| | | & | Bitwise and |
| | | ^ | Bitwise XOR |
| | | | | Bitwise OR |
| | | <, <=, >, >=, <>, !=, ==, is, is not | Relational Operators, Identity Operators |
| | | not | Boolean NOT |
| ↓ | and | Boolean AND |
| Lowest | or | Boolean OR |
