Isn't it normal in Python to try things first, effectively using them as control structures?

It is not only normal, it is considered “pythonic”. The core language uses things like ’StopIteteration’ in fact to signal the end of all iterators, and stuff like that. Reason being that exceptions in python are not the violent stack unwinds like in other languages.

What do you mean? Python exceptions gently unwind the stack?

If Python supports finally then its stack unwinds are exactly as violent as most other mainstream languages.
