Call python function with default arguments before other arguments?

Question

Can I call a function using the default value for some arguments but not for all?

Take numpy.random.lognormal(mean=0.0, sigma=1.0, size=None) as an example, I want to call it with default mean and sigma but not default size.

Something in my mind is like np.random.lognormal(_,_,2), but this does not work

Is it possible to do that?

Yes, this is possible. Simply provide the argument you want to override:

np.random.lognormal(size=2)

This is precisely where named arguments become useful.
