python - How can I call an instance function? -

i have class instance , phone call 1 of instance functions

udp_action = udpactions( application = self.application ) func = getattr( udp_action, 'udp_' + opts['cmd'] + '_fired' )

but i'm getting next error

values instance has no attribute '__getitem__'

where create mistake?

you're using opts if dictionary (or dictionary-like object), isn't.

it doesn't back upwards ['cmd'] notation, resulting in exception you're seeing.

in [1]: class values(object): pass in [2]: opts = values() in [3]: opts['cmd'] typeerror: 'values' object has no attribute '__getitem__'

python
