['root', '16788', '0.0', '0.1', '4944', '892', 'pts/1', 'R+', '11:57', '0:00', 'ps', 'xua']

['root', '    16788  0.0  0.1   4944   892 pts/1    R+   11:57   0:00 ps xua']
>>> tf = ts.split(" ",1)

['root']
>>> tf[0:]
['root', '    16788  0.0  0.1   4944   892 pts/1    R+   11:57   0:00 ps xua']
>>> tf[:1]
['root']
>>> tf[1:]
