Python-ese for indexing a list within a class

[Harry George]

How are you choosing to use a vs b ...?  I generally need to do this
with named objects so I use a map:
 class C:
     def __init__(self):
         counters={}
     def someFunction(self):
         # some code
         #---discover we need a counter for x---
         #---where x is "a", or "b", or whatever---
         cnt=self.counters
         if not cnt.get(x,0):
            cnt[x]=0
         cnt[x]=cnt[x]+1
