Answer 1

One method is to use ParameterGrid to make a iterator of the parameters you want and loop over it.

Another thing you could do is actually configure the GridSearchCV to do what you want. I wouldn't recommend this much because it's unnecessarily complicated.
What you would need to do is:

• Use the arg cv from the docs and give it a generator which yields a tuple with all indices (so that train and test are same)
• Change the scoring arg to use the oob given out from the Random forest.
