Two thoughts spring to mind:
-- is it possible to arrange the data model such that the value of the
thisflag is the index into the sequence, then:
def getflag(thisflag, results):
results[thisflag] += 1
return results
-- seriously "overengineered" for this particular example but the
replacement for switch statement is a dictionary and function pointers.
from functools import partial
def alt(thisflag, results):
def setflag(x):
results[x] += 1
{
0: partial(setflag, 2),
1: partial(setflag, 1),
2: partial(setflag, 0),
}[thisflag]()
return results
