Hi everyone
I've never used the module 'pickle' so far, thus I've got some questions about how to use it:
Lets say I have instances of class A and class B:
a = A()
b = B()
Is it possible to pickle both of these instances to the same pkl-file or will that have any bad impact for unpickle (i.e. the instance are 'mixed' or 'destroyed')? Or should I rather use a seperate file for every class instance I want to pickle?
Another very basic question about pickling class instances:
To store the value of attributes of an instance is it enough for the pickling-algorithm to use the __dict__ or do I have to implement the _setstate_ and _getstate_ function? I didn't really get the meaning of those while reading the python user manual...
Thanks in advance
