Question

我正在尝试显示用户友好的错误消息，同时还显示异常，但我似乎无法使其正常工作。

我尝试了这些，但是语法无效：

#First try:
except Exception as e, ValueError:
        print("\nThe program is unable to calculate the given equation. " +
            "Try Again!")
        print("\nError message " + e)
        continue

#Second try:
except ValueError, Exception as e:
        print("\nThe program is unable to calculate the given equation. " +
            "Try Again!")
        print("\nError message " + e)
        continue

如果有人可以帮助我，那就太好了。谢谢！

您可以使用追溯：

import traceback

#First try:
except ValueError:
        print("\nThe program is unable to calculate the given equation. " +
            "Try Again!")
        print("\nError message " + traceback.format_exc())
        continue

#Second try:
except Exception as e:
        print("\nThe program is unable to calculate the given equation. " +
            "Try Again!")
        print("\nError message " + traceback.format_exc())
        continue

指定错误类型时如何打印异常？
