numpy.s

numpy.s_()

A nicer way to build up index tuples for arrays.

For any index combination, including slicing and axis insertion, ‘a[indices]’ is the same as ‘a[index_exp[indices]]’ for any array ‘a’. However, ‘index_exp[indices]’ can be used anywhere in Python code and returns a tuple of slice objects that can be used in the construction of complex index expressions.
