 # 
 # This can be easily illustrated with an example that has more dimensions; we create an array with 4 dimensions and shape `(3,4,5,6)` and sum along the axis number 2 (i.e. the *third* axis, since in Python all counts are 0-based).  That consumes the dimension whose length was 5, leaving us with a new array that has shape `(3,4,6)`:
