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 |

â†‘ | ** | 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 |

â†“ | and | Boolean AND |

Lowest | or | Boolean OR |
