how to get a traceback and keep on running?

[Skaperen]

how to get a traceback and keep on running? i'd like to know because it can sometimes be useful. plus, it happened on its own with code i was working on, today. i forgot to save that output and where it happened would be nice to find. it has happened a couple times in the past, so i know something can do it.

import traceback

items = {}

try:
    items["NoKey"]
except KeyError:
    format_exc = traceback.format_exc()

print("Keep running")
print(format_exc)
