If you do not, then any code changes will be lost when you close the notebook, and the Comment tool will not become available. To make a copy, just after you open a notebook click the **Copy to Drive** button right below the menu bar and follow any prompts. The copied notebook will be opened and you will be able to preserve your code changes and comments."

Uses for **Jupyter Notebook** include: data cleaning and transformation, numerical simulation, statistical modeling, data visualization, machine learning, and much more. Here we are using **Colab** and **Jupyter Notebook** to create this interative Introduction to Programming in Python course."
