# Introduction The `Series.asfreq()` method in Pandas is used to convert a time series to a specified frequency. It allows us to fill in missing values or null values in the time series. This tutorial will guide you on how to use the `Series.asfreq()` method in Python Pandas. ## 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.
