Single Inheritance

 Main Syntax :

class Programmer(Employee):
    def __init__(self, aname, asalary, arole, alanguages):
        self.name = aname
        self.salary = asalary
        self.role = arole
        self.languages = alanguages

    def printprog(self):
        print(f"Name of programmer is {self.name}. Salary is {self.salary}. Role is {self.role}. Languages known are {self.languages}.")


harry = Employee("Harry", 255, "Instructor")
rohan = Employee("Rohan", 455, "Student")

shubham = Programmer("Shubham", 555, "Programmer", ['Python, C++'])
karan = Programmer("Karan", 777, "Programmer", "Python, Java")

print(karan.printprog())

Full Code:
class Employee:
    no_of_leaves = 89

    def __init__(self, aname, asalary, arole):
        self.name = aname
        self.salary = asalary
        self.role = arole

    def printdetails(self):
        return f"The Name is {self.name}. Salary is {self.salary} and role is {self.role}"

    @classmethod
    def change_leaves(cls, newleaves):
        cls.no_of_leaves = newleaves

    @classmethod
    def from_str(cls, string):
        return cls(*string.split("-"))

    @staticmethod
    def print_good(string):
        print("This is good " + string)

class Programmer(Employee):
    def __init__(self, aname, asalary, arole, alanguages):
        self.name = aname
        self.salary = asalary
        self.role = arole
        self.languages = alanguages

    def printprog(self):
        print(f"Name of programmer is {self.name}. Salary is {self.salary}. Role is {self.role}. Languages known are {self.languages}.")

  # You visited a restaurant called CodeWithHarry, and the food items in that restaurant are sorted, based on their amount of calories. You have to reserve this list of food items containing calories. # # You have to use the following three methods to reserve a list: # # Inbuild method of python # List name [::-1] slicing trick # Swapping the first element with the last one and second element with second last one and so on like, # [6 7 8 34 5] -> [5 34 8 7 6] # # Input: # Take a list as an input from the user # # [5, 4, 1] # # Output: # [1, 4, 5] # # [1, 4, 5] # # [1, 4, 5] # # All three methods give the same results! print ( "Welcome To Our Program \n " "Foods and Calories" ) # Take the size of the list from the user print ( "Enter the numbers of the list one by one \n " ) size = int ( input ( "Enter size of list \n " )) # Initialize a blank list mylist = [] # Take the input from the user one by one for i in range (size): mylist.app...
