# 异常处理
# 方式一
try:
    pass
except Exception as f:
    pass

# 方式二
try:
    pass
except Exception as e:
    pass  # try中代码异常，则此代码执行
finally:
    pass  # 无论是否出现异常，此代码都会执行,一般用于释放资源,如果try有return，则finally下面的代码会先执行再return

num1 = input("请输入第一个数值：")
num2 = input('请输入第二个数值：')
try:
    result = int(num1) * int(num2)
    print(result)
except Exception as e:
    print('输入错误')
finally:
    print('Goodjob!!!')

# 异常细分
try:
    pass
# except XXX as e:
#     pass
except Exception as e:  # 可以捕获所有错误
    pass

# 自定义异常
