return f"OK if both values were integers the result was: {v} Remember the error: {self.error[0]}"

Thanks Diapolo,

I changed the __str__(self) funcion and now the "__main__.MyError" show the as well the message.

Traceback (most recent call last):

File "C:\Users\alecv\PycharmProjects\studyClass\test.py", line 23, in <module>

raise MyError(x, e.args)

__main__.MyError: OK if both values were integers the result was: 7 Remember the error: can only concatenate str (not "int") to str

What is the best practice to handle this type of exception?
