如何在没有回溯的情况下进行异常处理？

Question

I have the function which you can see in the picture. How do I only return the last line only, when the exception is raised, without the other lines: traceback.., file"" etc.

def division(k, m):
    try:
        k / m
    except TypeError:
        raise ValueError ('hey') from None
    return k/ m

Answer 1

If you want to hide the exception, use pass instead of raising another exception.

def division(k, m):
    try:
        return k/m
    except TypeError:
        pass

If the exception occurs, this will return None by default. You could replace pass with a different return statement that returns whatever you want to use instead.

You shouldn't do the division again outside the try , since that will just get the error that you wanted to hide again.

Answer 2

Just put

import sys
sys.tracebacklimit = 0

Somewhere in your code. It will apply to all of your exception tracebacks though. I personally can't think of why I would do it, but knock yourself out!
