Code Correction: The following scikit-learn code is supposed to train a linear regression model and make predictions, but it has errors. Identify and fix ALL the errors. from sklearn.linear_model import linearRegression model = LinearRegression model.fit[X_train, y_train] predictions = model.predict[X_test] Write the corrected code below:

What is the difference between df.loc[] and df.iloc[]?
