4. In the Jupyter notebook, click the Activity01.01 directory and create a new notebook file with a Python3 kernel.
5. Import the os library and a random library, and define where our training and test data is stored using four variables, as shown in the following code:

   import os

   import random

   dataset_train_pos_path = "../Datasets/aclImdb/train/pos/"

   dataset_train_neg_path ...
