You could use string.lower (make sure you "import string"):

In [14]: commands
Out[14]:
['CLASS-MAP MATCH-ALL cmap1',
 'MaTch Ip AnY',
 'CLASS-map Match-Any cmap2',
 'MaTch AnY',
 'Policy-map policy1',
 'Class cmap1',
 'policy-Map policy2',
 'Service-PoLicy policy1',
 'claSS cmap2']

In [15]: commands_lower = [string.lower(f) for f in commands]

In [16]: commands_lower
Out[16]:
['class-map match-all cmap1',
 'match ip any',
 'class-map match-any cmap2',
 'match any',
 'policy-map policy1',
 'class cmap1',
 'policy-map policy2',
 'service-policy policy1',
 'class cmap2']
