Design a dental appointment system using python, with the following requirements. appointment as a super class, which contains four variables (m, d,y, desc) three sub classes (month, day, date). there should be appointments already created in a list and you are simply asking the users for a date to check against them. this mean that you need to create them ahead of time. there are several ways that you can approach this question. the example below is just one way of solving this problem. write a method called occurson inside each of the sub classes that checks whether the appointment occurs on that date (date), day (day) or month (month). ask the user to enter a date to check (for example, 2006 10 5), and ask to user if they want to check against date, day or month appointment. based on what the user selected, occurson inside each of the sub class should run and display any matching appointment and associated descriptions. submit your source codes (zipped) as well as screenshots of how your code ran. points will be deducted if there are no screenshots included in your submission.

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
