python max of list of arrays

Question

I have a list of arrays like:

a = [array([6,2]),array([8,3]),array([4,2])]

I tried max(a) which returns the following error:

Answer 1

The easiest way is to convert to tuple/lists for the sake of comparison (or implement the comparison yourself):

>>> max(a, key=tuple)
array([8, 3])

Note this is the builtin max and not np.max

EDIT:

For multi dimensional arrays, use the .tolist method:

max(a, key=operator.methodcaller('tolist'))
