The "start" and "finish" columns specify the range of columns to be
retrieved.
For example, start="age" and finish="height" would get you the age
column but would not include the name column. I would assume
"isAscending" is the order of the returned columns.

thanks a lot for this! it works.
can you pl. explain what start, finish, isAscending are?
also the value i pass to offset gets passed to cassandra as limit,
is this expected?
>>> client.get_slice(tablename='Table1', key='1',
columnParent='Standard1', start='', finish='', isAscending=True,
offset=-1, count=1000)
[column_t(columnName='age', value='24', timestamp=1246942866),
column_t(columnName='name', value='Chris Goffinet',
timestamp=1246943353)]
