Question

Could someone help me out with the following python question? Preferably using the "return a <= b < c" method instead of a standard if else statement. I would appreciate a step by step explanation if possible. Thank you!

Write a class called Appointment with methods as described below:

__init__() method

Define an __init__() method with four parameters:

• self

• name, a string indicating the name of the appointment (for example, "Sales brunch").

• start, a tuple consisting of two integers representing the start time of the appointment. The first integer represents an hour in 24-hour time; the second integer represents a number of minutes. For example, the tuple (10, 30) would represent 10:30 am.

• end, a tuple similar to start representing the end time of the appointment.

The __init__() method should create attributes name, start, and end, and use them to store the information from the parameters.

overlaps() method

Define an overlaps() method with two parameters, self and other, where other is another Appointment object.

This method should return True if self and other overlap and False if they do not. Be sure to return a boolean value rather than a string.

Note that two appointments overlap if

• the start time of one appointment occurs between the start and end times of the other appointment (including if the start times are equal), OR

• the end time of one appointment occurs between the start and end times of the other appointment (including if the end times are equal)

For this assignment, if the start time of one appointment is equal to the end time of the other appointment, the two appointments are not considered to overlap.

Code

class Appointment:
#init method
def __init__(self,name,start,end):
self.__name=name;
self.__start=start;
self.__end=end
#method overlaps
def overlaps(self,other):
#if other Appointment's start time is in between this Appointment' start time and end time then both Appointment overlaps
if other.__start[0]>=self.__start[0] and other.__start[0]<self.__end[0]:
return True
#if thos Appointment's start time is in between other Appointment' start time and end time then both Appointment overlaps
if self.__start[0]>=other.__start[0] and self.__start[0]<other.__end[0]:
return True

#if other Appointment's end time is in between this Appointment' start time and end time then both Appointment overlaps
if other.__end[0]>self.__start[0] and other.__end[0]<self.__end[0]:
return True

#if this Appointment's end time is in between other Appointment' start time and end time then both Appointment overlaps
if self.__end[0]>other.__start[0] and self.__end[0]<other.__end[0]:
return True

#if other Appointment's start time Hour is same as this Appointment's end time Hour but its minutes is before this Appointment's end time minutes both Appointment overlaps
if other.__start[0]==self.__end[0]:
if other.__start[1]<self.__end[1]:
return True
#if This Appointment's start time Hour is same as Other Appointment's end time Hour but its minutes is before Other Appointment's end time minutes both Appointment overlaps
if self.__start[0]==other.__end[0]:
if self.__start[1]<other.__end[1]:
return True
return False

ap1=Appointment("Test1",(14,20),(15,30))
ap2=Appointment("Test2",(13,20),(14,30))

if ap1.overlaps(ap2):
print("Yes overlaps")
else:
print("No overlaps")

output
