Forgot to mention that we are currently stuck with python2.5.2
As part of a debug/test hook, I would like to suspend further action of a
program, after a certain point in the procedure. What I had come up with is
a function named testHook() which does this:
choice = raw_input("Would you like to continue (Y or N): ")
if(str(choice).lower() != 'y'):
print("You chose not to go ahead. Ok!!\nAborting Now...")
raise Exception("User initiated Abort...")
raise # re-raise it..so we come out of execution loop
In this case, a stack trace gets printed out, before the string 'user
initiated abort' comes up. I want to remove that stack trace...so it looks
more clean to a user.
What can be done in this case? or any other way of creating such a hook?
Thanks and best regards,
