Python Programs on Classes and Objects, Classes and Functions, Classes and Methods

This video covers claases and objects, is as per VTU syllabus of B.E. 6th semester, Python Application Programming (17CS664).
In this video, Python programs are discussed on classes and objects, classes and functions and classes and methods.
Below programs are discussed in this video:
1) write a function called distance_between_points that takes two Points as arguments and returns the distance between them.
2) write a function named move_rectangle that takes a Rectangle and two numbers named dx and dy. It should change the location of the rectangle by adding dx to the x coordinate of corner and adding dy to the y coordinate of corner.
3)write a version of move_rectangle that creates and returns a new Rectangle instead of modifying the old one.
4) write a “pure” version of increment that creates and returns a new Time object rather than modifying the parameter.
5) write an init method for the Point class that takes x and y as optional parameters and assigns them to the corresponding attributes. Also write a str method for the Point class to print Point Object.
6) write an add method for the Point class that will add two Point objects.
7) write an add method for Points that works with either a Point object or a tuple:
If the second operand is a Point, the method should return a new Point whose x coordinate is the sum of the x coordinates of the operands, and likewise for the y coordinates.
If the second operand is a tuple, the method should add the first element of the tuple to the x coordinate and the second element to the y coordinate, and return a new Point with the result.
