Hello, I want to compute this:
G= graphs.CompleteGraph(4)
G.delete_edge({1,2})
L = [u for u in G.vertices()]
for x in L:
for y in L:
A = Set(G.neighbors(x))
B = Set(G.neighbors(y))
C= A.union(B)
if (C in Subsets(G.neighbors(1))):
print(x,y)
the result is :
(1, 1)
(1, 2)
(2, 1)
(2, 2)
but I don't want the function prints (1,1) & (2,2)
so what should I write in the function to omit these pairs?
