# Introduction In this lab, we will learn about the `isalpha()` function in the char module of the NumPy library. The `isalpha()` function checks if the characters in a string element are alphabets or not. If the characters are all alphabets, the function returns True, otherwise, it returns False. We can apply this function to an entire array of strings. ## 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.
