How can I iterate over the element of a set?

[Peder Jakobsen]

from sympy import *

H,B = symbols('H, B')

H = FiniteSet('A', 'B', 'C', 'E', 'F')

B = FiniteSet('Joe', 'Jack', 'Sue', 'Jill')

N = Union(H,B)

# how would I do something like this?

for n in N:

    #perform some operation

    foo(n)

Addendum:

In my case, I'd actually like to iterate over the set to create nodes and vertices in NetworkX

import networkx as nx

G = nx.DiGraph()

G.add_node("A")

G.add_node("B")

etc. 

G.add_edge("A", "B")

etc. 

# Then I can draw it in iPython notebook

nx.draw(G, node_size=90, node_color='Red')

It looks like that works.
