If you want to ignore some exception, you probably do something like this:

try:
lst = [1, 2, 3, 4, 5]
print(lst[10])
except IndexError:
pass

That will work (without printing anything), but contextlib let you do the same more expressively and semantically correct:

from contextlib import suppress
with suppress(IndexError):
lst = [1, 2, 3, 4, 5]
lst[10]
