为什么Finally在return语句之后执行？

Question

def Test():
    try:
        return 0
    finally:
        return 1
x  = Test()
print(x)

为什么上面代码的输出是1？ https://code.hackerearth.com/5cc081y 尽管从逻辑上讲控件将函数留在 return 语句中。

Answer 1

https://docs.python.org/2/tutorial/errors.html

"A finally clause is always executed before leaving the try statement, whether an exception has occurred or not. When an exception has occurred in the try clause and has not been handled by an except clause (or it has occurred in a except or else clause), it is re-raised after the finally clause has been executed. The finally clause is also executed “on the way out” when any other clause of the try statement is left via a break, continue or return statement.

Answer 2

finally 部分总是在离开 try 块之前执行。 return 0 将离开 try 块。所以 finally 部分首先执行， returns 1.
