Hello!
I have trouble with copy/deepcopy. It seems, I just don't understand something.
Please explain where things goes wrong and how to do it the right way.
I have one class:
class Distribution:
__gr_on_transp=dict()
__ostatok_m=dict()
and so on
And, I want to make full copy of it:
d1=Distribution()
d2=copy.deepcopy(d1)
But, members-dictionaries are don't copied. For example if I will write:
d1.clear()
which clears all two dictionaries, I will find that d2's dictionaries are also
empty!!!
Now I'am using the quick-hack:
class Distribution:
__gr_on_transp=dict()
__ostatok_m=dict()
...
def my_copy(self):
d2=copy.deepcopy(self)
d2.__gr_on_transp=self.__gr_on_transp.copy()
d2.__ostatok_m=self.__ostatok_m.copy()
return d2
It's work well, but I don't understand why previous is wrong and how to do it
in right way.
