Nor if you kill -9 the process, or get into an infinite loop, or any
number of other things. Specifically, what the finally block
guarantees is that it will be executed *before any code following the
try block*. In this example:
try:
code1
except Exception:
code2
else:
code3
finally:
code4
code5
Once you hit code1, you are absolutely guaranteed that code5 *will
not* be run prior to code4.
