How to launch getattr function in python with additional parameters?

问题

I want to call some unknown function with adding parameters using getattr function. Is it possible?

回答1:

Yes, but you don't pass them to getattr(); you call the function as normal once you have a reference to it.

getattr(obj, 'func')('foo', 'bar', 42)

回答2:

If you wish to invoke a dynamic method with a dynamic list of arguments / keyword arguments, you can do the following:

function_name = 'wibble'
args = ['flip', 'do']
kwargs = {'foo':'bar'}

getattr(obj, function_name)(*args, **kwargs)
