Write a program to extend the list class by adding a push method.
Vectors, in Physics, are objects that have both magnitude and direction. Design a class to represent vectors. Provide addition and subtraction operators - remember to adjust directions appropriately.
Write a wholeNumber class. The whole numbers are the nonnegative integers: 0,1,2, . . . Your class must handle addition, subtraction, and multiplication of whole numbers— no division or mixed-type (whole number and integer) operations need be handled. Your class must also handle printing, for example, if x is an instance of the wholeNumber class, you must be able to write: print(x).
Two cases must not be allowed: (1) you must not be able to create a wholeNumber that has a negative value; (2) an arithmetic operation cannot be allowed to have a negative result. In both cases, an error message must be printed.
Remember that arithmetic must return a whole number. That is, if x and y are whole numbers, the result of x + y must be a whole number.
Include sample code that uses your class and demonstrates the use of all methods as well as error handling.
