# Introduction This lab will guide you through the process of customizing `.rcParams` on the fly using Python Matplotlib. You will learn how to define functions in a custom module that set the defaults for figures, and how to use these defaults to create different sets of defaults for figures, such as one set for publication and another set for interactive exploration. ## VM Tips After the VM startup is done, click the top left corner to switch to the **Notebook** tab to access Jupyter Notebook for practice. Sometimes, you may need to wait a few seconds for Jupyter Notebook to finish loading. The validation of operations cannot be automated because of limitations in Jupyter Notebook. If you face issues during learning, feel free to ask Labby. Provide feedback after the session, and we will promptly resolve the problem for you.
