我该如何处理错误处理代码中的错误？

Question

我正在尝试执行此代码：

try:
    print(int(number1)*int(number2))
except ValueError:
    print(int(number1)*float(number2))
except ValueError:
    print(float(number1)*float(number1))
except ValueError:
   print(float(number1)*int(number1))

但是在完成代码之前发现错误。谁能帮帮我？

Answer 1

我假设你需要嵌套的 try / except:

number1 = '123'
number2 = '456.78'
try:
    print(int(number1)*int(number2))
except ValueError:
    try:
        print(int(number1)*float(number2))
    except ValueError:
        try:
            print(float(number1)*float(number1))
        except ValueError:
            print(float(number1)*int(number1))
