Hi,

Is there a way to store the solution obtained from Gurobi in one dictionary, where the dictionary key would be the variable name?

Gurobi has the command Model.getVarByName that can be used inside a for loop, but for our case, we found that this is a very slow process.

You could use Model.getAttr() to retrieve all of the variable names and values at once:
```
mvars = m.getVars()
names = m.getAttr('VarName', mvars)
values = m.getAttr('X', mvars)
result = dict(zip(names, values))
```
This should be a bit faster.
