Building the Right Environment to Support AI, Machine Learning and Deep Learning

All-Encompassing Try

I was told that in order to make my program easier to read, I should use try to cover all of my program, then catch every exception at the end of the program. Does this make any sense?

You should catch exceptions where you intend to handle them. It makes no sense to catch exceptions only at the end of a program when many exceptions are recoverable. For example, network servers need to be able to recover from network I/O errors. You can only do this if you catch exceptions at the point of an anticipated failure point. But you must ensure that you take proper fault-recovery steps. Only fatal and non-recoverable exceptions resulting in the termination of the program should be caught at the end of the program.
