Looks like you forgot to give one essential part of information in
your first email: varX aren't 'simple' integers or floats, but more
complex types. Not exactly what you gave in your example. Please do
give all the information if you're not sure what you're asking about
(it may even put people off in follow-up answering). Oh, and please
reply to the whole list, not just me: it'll enlighten other people as
well.
Anyway, with this, something like this (indeed a dictionary) would do
it:
vars = [var1, var2, var3]
dictvars = {}
for var in vars:
dictvars[var.value] = var
keys = dictvars.keys()
keys.sort()
sortedvars = [dictvars[key] for key in keys]
objSprites = pygame.sprite.OrderedUpdates(*sortedvars)
Arguably just as lengthly, but more consistent. Depending on the type
of 'varX' variable you're using, you might be able to simplify things
further (by using a dictionary instead of a home-made object, which I
assume the 'varX' variables are).
Probably putting up a solution here isn't really "tutoring", but I'm
curious if anyone else on the list has a cleaner solution than this.
Cheers,
Evert
