but of course (did you try it?). here's an outline:
dispatch = {
"something": somethingClass.func, # note: no () here
"somethingElse": somethingElseClass.func,
"anotherthing": anotherthingClass.func,
"yetanotherthing": yetanotherthingClass.func,
}
...
dispatch[value]() # note: do the call here!
or, a bit more robust:
try:
func = dispatch[value]
except KeyError:
print "- no handler for", value
else:
func()
tweak as necessary.
