Hi Mark,
I'm learning, too, so no bets this is best, but does this meet your needs:
.>>> def lower_list_o_strings(l):
nl = []
for s in l:
nl.append(s.lower())
return nl
.>>> l = ['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']
.>>> lower_list_o_strings(l)
['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']
Best,
Brian vdB
PS "No subject" is only marginally better than "HELP!!!!!!" ;-)
