Introduction
Numpy is one of the most powerful scientific computing libraries in Python. It provides a high-performance multidimensional array object, and tools for working with these arrays.
The numpy.char.replace()
function of the Numpy library is used to replace the occurrences of a substring in an array of strings or a string with a new substring. In this lab, we will learn how to use the replace() function to replace the content of an 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.
