Returning dictionary as result of a function

I created a mathematical model inside a function and solved it with Gurobi. I want to use the variable values and objective value obtained in the solution by passing them into another function.
So I want to get a dictionary with "return command" as the result of the function. When I try to do this, I get this error: <gurobi.Var *Awaiting Model Update*

1) How can I solve this problem?

2) Can I also get the result of more than one dictionary function with the "return command"?

Example:

(A_ik[i,k]=dicitonary)

 

def solve(...)

...

...

     return A_ik

  Hi,
  
  You can solve the problem after formulating it via calling model.optimize().
  I suggest you take a look a look at the Python examples to quickly see how to retrieve variable values and objective function vals: mip1.py.
  
  Full list of Python examples.
  
  Cheers,
