[Numpy-discussion] Functions vs Methods

It is said that function calls are expensive. Does that mean one must
use available methods instead?

Eg.  x is a NumPy array, and I need its transpose

Should I use

>>> x.T

>>> numpy.transpose(T)   ?

Does it matter which one I'm using ? If not, under what conditions
does it become important to think about this distinction?
