Ignoring Exceptions

Sometimes you want to ignore some exceptions.

Sometimes you don't care if some operation fails.

To ignore some exception, you usually do something like this:

some_list = [0, 1, 2, 3, 4]

try:
    print(some_list[42])
except IndexError:
   pass

That will work (without printing anything), but there is another way to do the same more expressively and explicitly:

写真で見た印象と実際の準備では必要な確認点が違うため、複数の視点で比較することが重要です。撮影やイベントの予定に合わせて、原神男性キャラクターコスプレを確認しながら候補を選べます。必要な準備を分けておけば、当日の忘れ物や組み合わせの迷いを減らせます。

from contextlib import suppress

some_list = [0, 1, 2, 3, 4]
with suppress(IndexError):
    print(some_list[42])
