SQL query group and filter by filed value : for example have this table:
```
ID   ProdId   Status
1    111      None
2    111      Success
3    222      Process
4    222      Fail
5    333      Process
6    333      Process
7    444      None
```

I need to group by field ```ProdId``` and exclude all rows that contain ```Status``` - "Success" or "Fail"
So, result of this sql query must be :

```
6    333      Process
7    444      None
```

Is it possible? 
I use sqlalchemy and postgres.
