Question

Declare a class named PatientData that contains two attributes named height_inches and weight_pounds. Sample output for the given program with inputs: 63 115 Patient data (before): 0 in, 0 lbs Patient data (after): 63 in, 115 lbs 1 Your solution goes here ' 2 1 test passed 4 patient PatientData () 5 print('Patient data (before):, end-' ') 6 print(patient.height_inches, 'in,, end=' ') 7 print(patient.weight_pounds, lbs') All tests passed 9 10 patient.height_inches = int(input()) 11 patient.weight_pounds = int(input()) 12 13 print('Patient data (after):', end-' ') 14 print (patient. height_inches, 'in,', end- ') 15 print(patient.weight_pounds, 'lbs') Run

Answer 1

Answer:

class PatientData():    #declaration of PatientData class

   height_inches=0  #attribute of class is declared and initialized to 0

   weight_pounds=0 #attribute of class is declared and initialized to 0

Explanation:

Here is the complete program:

#below is the class PatientData() that has two attributes height_inches and weight_pounds and both are initialized to 0

class PatientData():  

   height_inches=0

   weight_pounds=0  

patient = PatientData()  #patient object is created of class PatientData

#below are the print statements that will be displayed on output screen to show that patient data before

print('Patient data (before):', end=' ')

print(patient.height_inches, 'in,', end=' ')

print(patient.weight_pounds, 'lbs')

#below print  statement for taking the values height_inches and  weight_pounds as input from user

patient.height_inches = int(input())  

patient.weight_pounds = int(input())  

#below are the print statements that will be displayed on output screen to show that patient data after with the values of height_inches and weight_pounds input by the user

print('Patient data (after):', end=' ')

print(patient.height_inches, 'in,', end=' ')

print(patient.weight_pounds, 'lbs')      

Another way to write the solution is:

def __init__(self):

       self.height_inches = 0

       self.weight_pounds = 0

self keyword is the keyword which is used to easily access all the attributes i.e. height_inches and weight_pounds defined within a PatientData class.

__init__ is a constructor which is called when an instance is created from the PatientData, and access is required to initialize the attributes height_inches and weight_pounds of PatientData class.

The program along with its output is attached.
