| 运算符 | 描述 | 示例 |
|---|---|---|
| + | 加 | 2 + 4 = 6 |
| - | 减 | 2 - 4 = -2 |
| * | 乘 | 2 * 4 = 8 |
| ** | 幂 | 2 ** 4 = 16 |
| / | 除 | 2 / 4 = 0.5 |
| // | 除后向下取整 | 2 // 4 = 0 |
| % | 字符串翻译，或者求余数 | 2 % 4 = 2 |
| < | 小于 | 4 < 4 == False |
| > | 大于 | 4 > 4 == False |
| <= | 小于等于 | 4 <= 4 == True |
| >= | 大于等于 | 4 >= 4 == True |
| == | 等于 | 4 == 5 == False |
| != | 不等于 | 4 != 5 == True |
| () | 括号 | len(‘hi‘) == 2 |
| [] | 方括号（表示列表） | [1, 3, 4] |
| {} | 大括号（表示字典） | {‘x‘: 5, ‘y‘: 10} |
| @ | 修饰器符 | @classmethod |
| , | 逗号 | range(0, 10) |
| : | 冒号 | def x(): |
| . | 点 | self.x = 10 |
| = | 赋值 | x = 10 |
| ; | 分号（功能同换行） | print(‘hi‘); print(‘there‘) |
| += | 加后赋值 | x = 1; x += 2 |
| -= | 减后赋值 | x = 1; x -= 2 |
| *= | 乘后赋值 | x = 1; x *= 2 |
| /= | 除后赋值 | x = 1; x /= 2 |
| //= | 除后舍余并赋值 | x = 1; x //= 2 |
| %= | 求余后赋值 | x = 1; x %= 2 |
| **= | 求幂后赋值 | x = 1; x **= 2 |
