-#### 💡 Explanation
+#### 💡 说明:
 
-- `is not` is a single binary operator, and has behavior different than using `is` and `not` separated.
-- `is not` evaluates to `False` if the variables on either side of the operator point to the same object and `True` otherwise.
+- `is not` 是个单独的二元运算符, 与分别使用 `is` 和 `not` 不同.
+-  如果操作符两侧的变量指向同一个对象, 则 `is not` 的结果为 `False`, 否则结果为 `True`.
