Discussion on: I've never become overly convinced that switch statements are that much cleaner than `if else if else if else if else`

How would you handle a default case in this?

My though is to add || defaultValue at the end since a failure to match any property will return undefined. Thoughts?

That would be handy using a try except:

def my_switcher(x):
    switches = {
        'a': 1,
        'b': 2,
    }
    default = 3

    try:
        result = switches[x]
    except KeyError:
        result = default

    return result



print(my_switcher('a'))
print(my_switcher('b'))
print(my_switcher('c'))

I added the extra default variable just to make the code self explanatory.

EDIT: Bad solution, look at the other comments.
