executing finally clause executing finally clause 可以看到,虽然数字依旧是以string的格式输入,但执行了except TypeError语句,给出了该异常的handle语句,即int(x),int(y)改变了变量类型; 并且可以看到执行了else语句; 出现了两次finally语句是因为执行了一次divideNew('4','3'),又执行了一次divideNew(int('4'),...

使用try…except…else 语句控制流程 以下示例演示了如何使用 try...except...else clause 开发一个计算体重指数(BMI)的程序: 首先,创建一个基于身高和体重计算 BMI的函数: defcalculate_bmi(height,weight):""" calculate body mass index (BMI) """returnweight/height**2 ...
上面的输出是这样的,因为只要python尝试访问b的值,NameError就会发生。 尝试使用else子句 在Python中,你也可以在try-except块上使用else子句,它必须出现在所有except子句之后。只有当try子句没有引发异常时,代码才进入else块。 # Program to depict else clause with try-except# Python 3# Function which returns a...
We believe this should be fixed upstream in Python itself until that we remove support fortry/except*from RestrictedPython. (It has been fixed for some Python versions.) Patches Patched in version 8.0 by removing support fortry/except*clauses ...
[1]"executing finally clause"[1]0.5 AI代码助手复制代码 我是先finally,再return,所以会是上述的输出结果。 2)情形二 输入: divide(1,0) AI代码助手复制代码 输出: [1]"executing finally clause"[1] Inf AI代码助手复制代码 注意,R会输出Inf,这点与Python不同。
