Class difflib. HtmlDiff
This class can be used to create HTML tables (or html files containing tables). The two sides correspond to the presentation or comparison results of rows.
Make_file (fromlines, tolines [, fromdesc] [, todesc] [, context] [, numlines])
Make_table (fromlines, tolines [, fromdesc] [, todesc] [, context] [, numlines])
The preceding two methods can be used to generate an html file containing a table whose content
represented as follows:

This class can be used to create an HTML table (or an HTML file that contains a table), with both sides corresponding to the display or row to show the difference results.
make_file (Fromlines, Tolines [, fromdesc][, todesc][, context][, Numlines])
make_table (Fromlines, Tolines [, fromdesc][, todesc][, context][, Numlines])
All two of these methods can be used to generate an HTML file containing a table with a comparison of the results, an

The keyword instanceof tells us whether the object is an instance of a particular type (instance or "instance"). It returns a Boolean value, to use in the form of a problem, as follows: if (x instanceof Dog) ((DOG) x). Bark (); Styling x to a DOG before the IF statement checks if object x is subordinate to the Dog class. Before styling, if there is no other information to tell
