# Introduction In this lab, we will walk through an example of using the Pandas DataFrame `last()` method. The `last()` method allows us to select the last few rows of time series data based on a date offset. This can be useful when working with dataframes that have dates as the index. The method returns the dataframe with the selected rows, and it raises a `TypeError` if the index is not a DatetimeIndex. ## 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.
