Crashes also happen from Recursion if not careful. Idk why but it happens. Although some of it is probably by not using try / catch probably anywhere in the python source code as a safeguard. I always like try / catch even in C++ as you never know when crap might happen to make things crash. A Perfect Example is a Access violation.

(Yes I have this is a Standard for me and it gets me to great quality code)
(this makes me wonder if Windows does not use try / catch anywhere. It would be nice if Microsoft Required try / catch in every function for drivers as well to hopefully make them more stable.)

All I know is I like having a lot of Checks (even if not required) that can actually prevent any and all exceptions to begin with.

And yes from what I learned from experiance myself. Always use try and catch anything before it is to late will help you in the long run.

(not to mention I blame Microsoft for not replacing their current Windows Update for when Updates Fail with a Detailed list of the names of the update(s) that failed and a description of what the reason is without Error code(s) as the Codes does not tell crap about why they failed. So, yeah I point my fingers at whoever wrote Windows Update, to fix their crap. As this is a issue in windows 7 SP1, 8, 8.1, and 10.)
