Question

In Objective-C you can do [variable valueForKeyPath:@"abc.def"] or [[variable abc] def] and if abc doesn’t exist on variable you’ll get a nil value in the end and will not get an error or exception. This is really convenient. Is there something like this in Python? I know you can do (for dictionaries at least)

abc = variable.get('abc', None)
if abc:
    def = abc.get('def', None)

or

try:
    def = variable.get('abc').get('def')
except:
    pass

which seems incredibly verbose. Is there an easier way when I just want to access an object’s attribute or get a None value back?

Answer 1

what about

def = variable.get('abc', {}).get('def',None)

well, this will only work for dict..
