As a first suggestion, if you want to create a SymPy object, I would
suggest to inherit from sympy.core.basic.Basic, something like this:
class YourClass(Basic):
# constructor:
def __new__(cls, arg1, arg2, ... ):
obj = Basic.__new__(cls, arg1, arg2, ... )
return obj
@property
def arg1(self):
return self.args[0]
@property
def arg2(self):
return self.args[1]
An alternative would be to put *obj._arg1 = arg1* in the constructor, the
*return
self._arg1* in the properties.
In this way, some functions such as __eq__ and __hash__ will be
automatically defined, __eq__ will compare the constructor arguments, and
it's probably going to be more efficient, as SymPy's core uses hashes.
