Introduction
The at_time()
method in Pandas is used to select values of rows at a particular time of day. It can be used to filter a DataFrame based on a specific time. If the specified time is not present in the DataFrame, it returns an empty DataFrame. This method is particularly useful for time series analysis. In this lab, we will learn how to use the at_time()
method with pandas DataFrame.
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.
