pickling problem

[Brian Blais]

Hello,

I have a somewhat nested dict that I want to pickle, but it (sometimes) contains some
no-no's (specifically, in this case, functions). I know I can't pickle them, but I
would like to be able to pickle the rest of the dict. Is there a good way to be able
to walk through a dict, and take out all of the non-pickleable objects? I could
replace them with something else (a tag of some sort, for me to reconstruct things
later).


thanks,

Brian Blais

One way to do that could be:

d = {1:functionA, 2:functionB, 3:"String"}
for key in d:
if callable(key): d[key] = "tag"

That would work for the functions in your dictionary.
