I have made a script that includes an exception for ValueError, however when the exception does not run when there is a ValueError

Value Error Exception

What happens when I run it

CodePudding user response：

The condition that raises the "ValueError" exception should be inside the try except block. In this case the function that raise the exception is int() because you try to convert a letter 'e' to an integer.

So you should do something like this:

try:
 ans= int(input("Answer:")) # <--- this raises the exception
 do_something()
except ValueError:
 print("This is raised if the argument of int() function is a string")

As shown in this MDN Doc you should use the exceprionVar parameter into the catch block and then check if (exceptionVar instanceof ValueError)
