zeros after

[s-celles]

We have

In [9]: ring.all
Out[9]: array([ 2.1,  1.2,  0. ,  0. ,  0. ,  0. ,  0. ,  0. ,  0. ,  0. ])

which is displayed as

array([ 0. ,  0. ,  0. ,  0. ,  0. ,  0. ,  0. ,  0. , 1.2,  2.1 ])

we might also have a method to display data as

array([ 1.2,  2.1, 0. ,  0. ,  0. ,  0. ,  0. ,  0. ,  0. ,  0. ])

which should be

In [10]: ring.????
Out[9]: array([ 0. ,  0. ,  0. ,  0. ,  0. ,  0. ,  0. ,  0. , 2.1,  1.2 ])
