Inscrutable error

[Led_Zeppelin]

This is the code where it happens. I posted the error down below and it gives a hint as to where the error is.

cv=TimeSeriesSplit(gap=0, max_train_size=None, n_splits=5, test_size=None)
estimator=XGBClassifier(
        base_score=None,
        booster=None,
        colsample_bylevel=None,
        colsample_bynode=None,
        colsaample_bytree=None,

        validate_paramters=None,
        verbosity=None,
    )

SyntaxError: positional argument follows keyword argument

I am guessing it tells us that the error is in the first few python lines I do not think that the number 1 surrounded by brackets means a lot. If I were to run the code again that one would probably change to two.

What exactly am I looking for?

As I said it is in the first couple of lines. I just do not know what I am looking for.

I use black for code formatting, and it does not flag anything like this error when I run it.

Any help appreciated.

Respectfully,
