Save and load initialized class

[Bob van der Poel]

I'm trying to something simple (yeah, right). Mainly I want to have a bunch
of variables which my program needs and uses to be in a saveable/loadable
block. Currently I have then all as a bunch of globals which works, but
trying to keep track of them and the correct spellings, etc becomes a bit
of maintenance nightmare. So, demonstrating all my cleverness I came up
with:

class Opts():
     var1 = 123
     var2 = "hello world"

Notationally, it looks much like the variables are stored in a separate
module. I can call these options from within a function with the simple
notation:

      if Opts.var1 == 99 ...

And, if I need to change a value I can:

     global
     Opts.var1 = 0

Further, and importantly, I can save the lot with:

  json.dump(Opts.__dict__, open("mybuffer", "w"))

But, I can't figure out how to load the saved data back into my program.
Doing

  z=json.load (open("mybuffer", "r"))

loads a dictionary ... which makes sense since that is what I saved. So,
can I now reset the values in Opts from a saved dictionary?

Best,
