Fit logistic regression model

Logistic regression is a simple yet very powerful classification model that is used in many different use cases. You will now fit a logistic regression on the training part of the telecom churn dataset, and then predict labels on the unseen test set. Afterwards, you will calculate the accuracy of your model predictions.

The accuracy_score function has been imported, and a LogisticRegression instance from sklearn has been initialized as logreg. The training and testing datasets that you've built previously have been loaded as train_X and test_X for features, and train_Y and test_Y for target variables.
