When an error occurs, the interpreter prints an error message and a stack trace.
In interactive mode, it then return to the primary prompt; when input came from a file, it exist with a nonzero exit status after printing the stack trace.
(Exceptions handled by an except clause in a try statement are not errors in this context.)
Some errors are unconditionally fatal and cause an exit with a nonzero exit; this applies to internal inconsistencies and some cases of running out of memory.
