Hi, I would like to be able to switch between swiginac and sympy
objects to be able to test both packages (for a while). I have a
problem with multiplication with sympy objects.
import swiginac
import sympy
x = swiginac.symbol("x")
y = sympy.Symbol("y")
class Foo:
def __init__(self):
self.field = 1.0
def __mul__(self, other):
print "Multiplication in Foo from right"
self.field = self.field * other
def __rmul__(self, other):
print "Multiplication in Foo from left"
self.field = other * self.field
f = Foo()
f*x # works
x*f # works
f*y # works
y*f # does not work
What should I do about this ?
