     >>> "HELLO_GOODBYE_xxxxxxxx.ls".rpartition('_')
    ('HELLO_GOODBYE', '_', 'xxxxxxxx.ls')
     >>> "HELLO_GOODBYE_xxxxxxxx.ls".rsplit('_', 1)
    ['HELLO_GOODBYE', 'xxxxxxxx.ls']
     >>> "HELLO_GOODBYE_xxxxxxxx.ls".rpartition('_')[0]
    'HELLO_GOODBYE'
     >>> "HELLO_GOODBYE_xxxxxxxx.ls".rsplit('_', 1)[0]
    'HELLO_GOODBYE'


For the future, getting help works better if you show what you tried, 
and what it produced.
