Answer to Question #350991 in Python for Gaurav

Question

Write a Python program to demonstrate multiple inheritance.

1. Employee class has 3 data members EmployeeID, Gender (String), Salary and

PerformanceRating(Out of 5) of type int. It has a get() function to get these details from

the user.

2. JoiningDetail class has a data member DateOfJoining of type Date and a function

getDoJ to get the Date of joining of employees.

3. Information Class uses the marks from Employee class and the DateOfJoining date

from the JoiningDetail class to calculate the top 3 Employees based on their Ratings and then Display, using readData, all the details on these employees in Ascending order of their Date Of Joining.

Answer 1

import datetime as dt


class Employee:
    def __init__(self, id: str, gender: str, salary: int, perfomance_rating: int):
        self.id, self.gender, self.salary, self.perfomance_rating = id, gender, salary, perfomance_rating
    
    def get_id(self):
        return self.id
    
    def get_gender(self):
        return self.gender
    
    def get_salary(self):
        return self.salary
    
    def get_perf_rat(self):
        return self.perfomance_rating    


class JoiningDetail(Employee):
    def __init__(self, id: str, gender: str, salary: int, perfomance_rating: int, date: dt.date):
        super().__init__(id, gender, salary, perfomance_rating)
        self.date = date
    
    def get_DoJ(self):
        return self.date
    
    def __str__(self):
        return f"id {self.id} : {self.date}"


class Information:
    def __init__(self, e_list):
        self.e_list = e_list
    
    def readData(self):
        N = len(self.e_list)
        for i in range(N-1):
            for j in range(N-i-1):
                if self.e_list[j].get_perf_rat() > self.e_list[j+1].get_perf_rat():
                    self.e_list[j], self.e_list[j+1] = self.e_list[j+1], self.e_list[j]
        
        for i in range(3):
            for j in range(2 - i):
                if self.e_list[j].get_DoJ() > self.e_list[j + 1].get_DoJ():
                    self.e_list[j], self.e_list[j+1] = self.e_list[j+1], self.e_list[j]
        
        return '\n'.join(list(map(str, self.e_list[:3])))

How to use:
1) Make some Employees using JoiningDetail class
2) Give the list of employees to Information class and print(readData)


Example of usage:
temp = [('1', 'm', 10, 5, dt.date(2000, 10, 30)), ('2', 'f', 5, 3, dt.date(2001, 10, 12)), ('3', 'm', 100, 10, dt.date(1998, 10, 1))]
lst = Information([JoiningDetail(*i) for i in temp])
print(lst.readData())
