Jessie gave some really good example of how to simply using the pickle module.
But it seemed like you took only the call to the pickle module and ditched the
rest ;-)
There is absolutely no reason to use more than one file here. The point of
using pickle is that you can store entire object structures, and not multiple
lists in different files that must be joined back up again with nested for
loops.
Trying to change as little as possible from your last example...
#########
import pickle
### Exporting
values = []
sel=cmds.ls(sl=1,mat=1)
for materials in sel:
attr = materials + '.diffuseColorAmount'
diffColorAmmount = cmds.getAttr(attr)
data = (attr, diffColorAmmount)
values.append(data)
with open( "c:/MayaStore/MaterialsValue.p", "wb" ) as f:
pickle.dump(values, f)
### Importing
with open( "c:/MayaStore/MaterialsValue.p", "rb" ) as f:
valList = pickle.load(f)
for data in valList:
attr, val
cmds.setAttr(attr, val)
#########
In this example what we do is store the attribute and the value together as a
tuple. This all goes into one file as a list of tuples. Then we can read back
that list, and pull out the tuples already matched up and call setAttr. This
immediately makes it more flexible because you can store any attribute name and
value and call setAttr with those objects.
You can get more flexible than this by using structures like a dict to maintain
more information in each item.
