Introduction to the display function

The display function is a built-in function of IPython that is used to display graphical representations or other formatted output of Python objects , such as images, audio, video, HTML, etc.,         in the Jupyter Notebook environment .
        The display function can accept one or more arguments, each of which is a Python object. It will automatically select the appropriate display method according to the type of object and display it in Jupyter Notebook . If you need to display multiple objects in the same cell, you can list these objects one by one in the display function.
