Perhaps a dictionary?
Something like:
myObjects = { 'A':MyObject(id=1), 'B':MyObject(id=2), 'C':MyObject(id=3) }
for c in ('A', 'B', 'C'):
if segment.upper().startswith(c):
myObjects[c].doSomething(segment)
If your MyObject instances are going to be constructed in a systematic
way, then you could simplify your definition of myObjects a bit more.
Eg:
objectData = [('A', 1), ('B', 2), ('C', 3)] # etc
myObjects = dict([(c, MyObject(id=id)) for c, id in objectData])
Hope this helps!
