Ignoring 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:

from contextlib import suppress

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