Python's built-in `set` class removes duplicates automatically (if you
make sure to sort the indices so that each edge always has the same
representation):
edges = set()
def add_edge(v1, v2):
edges.add((min(v1, v2), max(v1, v2))
for i in xrange(x.nsimplex):
add_edge(x.vertices[i,0], x.vertices[i,1])
add_edge(x.vertices[i,0], x.vertices[i,2])
add_edge(x.vertices[i,0], x.vertices[i,3])
add_edge(x.vertices[i,1], x.vertices[i,2])
add_edge(x.vertices[i,1], x.vertices[i,3])
add_edge(x.vertices[i,2], x.vertices[i,3])
You can then iterate over edges directly, or call `list(edges)` if you
need them in an ordered list.
