Poly.copy()
Poly.fromkeys(iterable[, value])
Poly.get(k[,d])
Poly.is_exact_type(other)	Check whether the supplied argument is a poly having the same keyfor.
Poly.items()
Poly.keys()
Poly.merge(other)	Merge another poly having the same keyfor attribute.
Poly.mul_poly(other, keyIndexes, keyfor)	Multiply by another poly of different type and return a new poly.
Poly.pop(k[,d])	If key is not found, d is returned if given, otherwise KeyError is raised.
Poly.popitem()	as a 2-tuple; but raise KeyError if D is empty.
Poly.remove_zero()	Remove any item having value 0.
Poly.set_keyfor(names)	Set the keyfor attribute for the poly.
Poly.setdefault(k[,d])
Poly.update([E, ]**F)	If E present and has a .keys() method, does: for k in E.keys(): D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v
