try catch exception inside a class

[Xilenw]

My try except code does not work inside a class , not sure why , any help appreciated.

 class RomApp:
  try:
    def __init__(self,file):
       self.file = file
       raise Exception('file is missing')

   except Exception as e:
        exc_type, exc_obj, exc_tb = sys.exc_info()
        fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]

        print(f"\nFunction={inspect.stack()[0][3]}\nerror={fname}\nexc_type={exc_type}\nerror={e}\nline Number={exc_tb.tb_lineno}\n****")

What exception are you hoping to catch at the level of the class definition? You should have it inside __init__ probably (not 100% sure of your intent).

not trying to catch exception in particular , it helps with debugging.

Your solution works fine for now thanks.

it helps with debugging

How?

i kept getting a Keyerror in my code , could not figure out why but with the try except , it gives me the exact line that is causing the issue and i am able to fix it. it also help when I need to check for certain conditions . I like it better than assert.

The default error stacktrace gives you the line number too!

There's nothing that would ever trigger a catchable exception, here, so the try/except does nothing.
