re is not always the right tool to be used.
Without more precisions:

>>> s = '2.201000e+01 2.150000e+01 2.150000e+01\
...  : (instance: 0)       :       some description'
>>> s
2.201000e+01 2.150000e+01 2.150000e+01 : (instance: 0)       :
some description
>>> s[:s.find(':')]
2.201000e+01 2.150000e+01 2.150000e+01
>>> s[:s.find(':')].split()
['2.201000e+01', '2.150000e+01', '2.150000e+01']
