#### 💡 Explanation: #### 💡 说明:
- When a `return`, `break` or `continue` statement is executed in the `try` suite of a "try…finally" statement, the `finally` clause is also executed ‘on the way out. - 当在 "try...finally" 语句的 `try` 中执行 `return`, `break` 或 `continue` 后, `finally` 子句依然会执行.
- The return value of a function is determined by the last `return` statement executed. Since the `finally` clause always executes, a `return` statement executed in the `finally` clause will always be the last one executed. - 函数的返回值由最后执行的 `return` 语句决定. 由于 `finally` 子句一定会执行, 所以 `finally` 子句中的 `return` 将始终是最后执行的语句.
