Please visit the following (LINK) to have access the google colab file.

At this cell (LINK), I am trying to write the following constraint

### Constraints
- **Maximum investment** 
x_1 + x_2 = a

I have tried the following code

m.addConstr(sum(StockWeight[i] for i in range(0,2)) == MaxInvest, name = 'MaxInvest')

but the output is wrong.

Could you elaborate what exactly is wrong with this constraint?

The code you wrote adds the constraint
```
MaxInvest: StockWeight[0] + StockWeight[1] = MaxInvest
```
