Debug Logging

In am, you can put a print statement in that function where you print the two ints and what you think the sum is before you return. Another thing you can have is a rolling files. A lot of people just leave the prints in, but now your programm becomes really slow,. printing to the screen halts the processer and things like that. And then every day i'll dilete the file and start over. But logging can still be problematic because they're very hard to track through if only a couple of them are having problems Track through all that mass of amount of data you've generated looking for problems.
