I dont see how anything can beat MRABs in declarativeness, neatness succinctness
s= "14 *0 330 *0 760 411|0 0 770g 1544g 117g 1414
computedshopcartdb:103.5% 0 30|0 0|1 19m 97m 1538
ComputedCartRS PRI 09:40:26"
>>> split('[ |]+', s)
['14', '*0', '330', '*0', '760', '411', '0', '0', '770g', '1544g', '117g',
'1414', 'computedshopcartdb:103.5%', '0', '30', '0', '0', '1', '19m', '97m',
'1538', 'ComputedCartRS', 'PRI', '09:40:26']
And if you dont mind two steps here is another longer-looking but more
straightforward (IMHO of course):
>>> [z for y in s.split() for z in y.split('|')]
['14', '*0', '330', '*0', '760', '411', '0', '0', '770g', '1544g', '117g',
'1414', 'computedshopcartdb:103.5%', '0', '30', '0', '0', '1', '19m', '97m',
'1538', 'ComputedCartRS', 'PRI', '09:40:26']
