Python exception handling best practice?

Question

I like to prepare a boilerplate code for exception handling that I can routinely use with shortcuts in my IDE.

I have made this code below as a first attempt. Is it OK for general purposes? Any suggestion for improvement?

try:
# actual code comes here:
pass
# can multiplied for other types of known exceptions:
except IndexError as err:
print("IndexError: {0}".format(err))
exit(1)
# for unexpected errors:
except Exception as inst:
print(type(inst)) # the exception instance
print(inst.args) # arguments stored in .args
print(inst) # __str__ allows args to be printed directly
exit(2)

Answer 1

Prof. Dr. Zoltán Vass, I used my sample in a previous answer, where the question about raising user exceptions has been coming up.

Answer 2

I like and use this very basic approach:

Thanks for your suggestion. I also prefer simplicity. In your code, why did you include the line below?

“raise Exception # not needed”
