Want to whittle a list like this:

[u'Espa\xf1ol', 'Health & Fitness Clubs (36)', 'Health Clubs & 
Gymnasiums (42)', 'Health Fitness Clubs', 'Name', 'Atlanta city guide', 
'edit address', 'Tweet', 'PHYSICAL FITNESS CONSULTANTS & TRAINERS', 
'HEALTH CLUBS & GYMNASIUMS', 'HEALTH CLUBS & GYMNASIUMS', 
'www.custombuiltpt.com/', 'RACQUETBALL COURTS PRIVATE', 
'www.lafitness.com', 'GYMNASIUMS', 'HEALTH & FITNESS CLUBS', 
'www.lafitness.com', 'HEALTH & FITNESS CLUBS', 'www.lafitness.com', 
'PERSONAL FITNESS TRAINERS', 'HEALTH CLUBS & GYMNASIUMS', 'EXERCISE & 
PHYSICAL FITNESS PROGRAMS', 'FITNESS CENTERS', 'HEALTH CLUBS &

'Support', 'Terms of Use', 'Privacy Policy', 'Advertise With Us', 
'Add/Update Listing', 'Business Profile Login', 'F.A.Q.']

Want to keep all elements containing only upper case letters or upper 
case letters and ampersand (where ampersand is surrounded by spaces)

Is it easier to extract elements meeting those conditions, or remove 
elements meeting the following conditions:

* elements with a lower-case letter in them
* elements with a number in them
* elements with a period in them

?


So far all I figured out is remove items with a period:
newlist = [ x for x in oldlist if "." not in x ]


Thanks for help, python gurus.
