python try exception finally记录

try exception finally中,finally下的语句块始终会执行

测试finally代码

def test_try_exception(a, b):
'''测试异常捕获语句''' result = -1
try:
result = a/b # 流程语句
except ZeroDivisionError as e:
return 0 # 异常时执行
else:
return result # 无异常时执行
finally:
return 1 # 无论如何都会执行,上面的else中返回语句会执行,但执行完后还会执行finally中语句 if __name__ == '__main__':
print(test_try_exception(1,2))
