Exercise

Prepare a submission

You've already built a model on the training data from the Kaggle Store Item Demand Forecasting Challenge. Now, it's time to make predictions on the test data and create a submission file in the specified format.

Your goal is to read the test data, make predictions, and save these in the format specified in the "sample_submission.csv" file. The rf object you created in the previous exercise is available in your workspace.

Note that starting from now and for the rest of the course, pandas library will be always imported for you and could be accessed as pd.
