My input:
-----------------------------------------------------
#!/usr/bin/env python2.2

from set import set

"""Making graph from adjency matrix"""

adjency = [
  [0, 0, 1, 1, 0, 0, 1],
  [1, 0, 0, 1, 0, 0, 1],
  [0, 1, 1, 0, 0, 0, 1],
  [1, 0, 1, 1, 0, 0, 0],
  [0, 0, 1, 1, 1, 0, 1],
  [0, 0, 1, 1, 0, 1, 1],
  [0, 1, 1, 1, 0, 0, 0],
]

V = set(range(len(adjency)))
E = set([(i, j) for i in V for j in V if adjency[i][j]])
G = (V, E)

print G
