Python: How to update an attribute programmatically? [duplicate]

Question

I'm looking for a way to update an attribute programmatically (especially when inside an update() function of an SQLAlchemy class)

def update(self, **kwargs):
    for kwarg in kwargs:
        setattribute(self, kwarg, kwargs[kwarg])

This does not seem to work, neither this:

def update(self, **kwargs):
    for kwarg in kwargs:
        self[kwarg] = kwargs[kwarg]

I'm not sure what you're doing, but this doesn't look like a good idea to me. You usually want to keep data out of your variable names — That1Guy

def update(self, **kwargs):
    for key, value in kwargs.items():

kwargs is a dict, you can iterate on its keys and values with items():

def update(self, **kwargs):
    for key, value in kwargs.items():
        setattr(self, key, value)
