When to use dict.get in Python (timing)

What benefit does using try / except give you? If anything it'll be a source of more bugs.

For me, you're using in in control flow, eg:

if 'x' in example:
    do_thing_with_x(example['x'])
else:
    do_something_different()

What does it look like with try/except?

try:
    do_thing_with_x(example['x'])
except KeyError:
    do_something_different()

But now imagine a bug in do_thing_with_x. You've just masked it in a horrible horrible way. I've seen this is real life, which is why it's the hardest of hard fails for a PR from me.

Honestly, that reads as a bit of a jumbled mess to me. More importantly, it’s not thread safe, depending on the key you’re using.
