Comment #35 on issue 1923 by nicolas.pourcelot: count_ops doesn't return a
count (by default)
http://code.google.com/p/sympy/issues/detail?id=1923
Well, I personally don't mind.
Concerning style, however, I would write it as following :
elif isinstance(expr, Expr):
return expr.count_ops(visual)
return NotImplemented
or
elif isinstance(expr, Expr):
return expr.count_ops(visual)
raise NotImplementedError
Note that since Expr is a subclass of Basic, "not isinstance(expr, Expr) or
not isinstance(expr, Basic)" is a verbose equivalent of "not
isinstance(expr, Expr)".
