I have created a ticket here:
https://trac.sagemath.org/ticket/27709
and now made the vector method output a copy.

You received this
Can you provide details of how you created the polyhedron? As David said,
Q.vertices() should make a copy before returning the result, and I would

Thank you David. Using deepcopy seems to solve the issue if I make a
separate copy after the call. But as you mentioned, the return of function
should be a copy object.

You probably want deepcopy. That being said, Q.vertices should probably
also make a copy before returning the result.

I have recently created a Polyhedron Q that corresponts to the cuts of a
graph.
Once I have Q, I created a list of vectors of its vertices as follows:
V=[s.vector() for s in Q.vertices()]
Now I create a copy of V
W= copy(V)
Then I change the 6th co-ordinate of each vector in W as follows
