title: print constraints Gurobi Python
body: <p>I'm using Gurobi in Python and for a given set <code>S</code> I'm adding the constraint as follows:</p>
  
  <pre><code>for i in S:
    m.addConstr(quicksum(x[i,j] for j in (set(V) - set(S))) &gt;= 2)
  </code></pre>
  
  <p>I want to print these constraints for each value of the sets <code>S</code> and <code>V</code> on the screen. 
  For an example, if <code>S={1,3,4}</code> and <code>V= {1,2,3,4,5,6}</code>, then, my constraint will be <code>x[1,2]+x[1,5]+x[1,6]+x[3,2]+x[3,5]+x[3,6]+x[4,2]+x[4,5]+x[4,6]&gt;=2</code>
  I want this constraint to be preinted on the screen.
  Can someone please help me to do it? </p>
