Yes Libu, Ludo is right.

for you case you should write your create method as below.

def create(self, cr, uid, vals, context=None):
if vals.get('account_name', False):
lower = vals.get('account_name', False)
value=lower.upper()
vals.update({'account_name':value})
return super(hotel_account,self).create(cr,uid,vals,context=context)

You are using a self browse in a create, trying to go over all existing records when creating a new record and you are using "vals" when browsing as the ids. This does not make sense to me?

Anyway, the result of that browse will most likely by an empty list and a Nonetype actually has no account_name :)

Actualy, Ludo gave half precise answer :)
that self.browse method will do apsolutly nothing, you did not send ids to it so it will always return null...

when you are createing record, you are apssing a lis of values (vals) in dictionaly form {'key':value}
now if you need uppercase name saved...
probably the easiest way is to remove complete browse  part and instead just update vals:
vals['account_name'] = vals['account_name'] and vals['account_name'].upper or False
and then return super call to
