I am trying to define class, where if I use a statement a = b, then instead of
"a" pointing to the same instance as "b", it should point to a copy of "b", but
I can't get it right.
Currently, I have the following:
----
class myclass(object):
def __init__(self, name='')
self.name = name
def copy(self):
newvar = myclass(self.name)
return newvar
def __eq__(self, other):
if instance(other, myclass):
return self == other.copy()
return NotImplemented
----
Now if I try:
>>> a=myclass()
>>> a.name = 'test'
>>> b=a
>>> b.name
'test'
>>> b.name = 'test2'
>>> a.name
'test2'
I wanted b=a to make a new copy of "a", but then when I assigned b.name =
'test2', even a.name became 'test2'.
How can I rectify my code to make the __eq__() behave like copy()?
Thanks
