Create a class: "Palindrome" with private data members: upper limit (int), lower limit (int) and parameterized constructor, which initializes the values of both data members. Apart from initialization, this constructor also displays the count of palindrome numbers from upper_limit to lower_limit. [Example: upper limit:50, lower_limit:10, count of palindrome numbers is: 4(11 , 22, 33 and 44), also make sure the value of upper_limit should be greater than lower limit].
. In the above class (MyClass), overload __add__, __eq__, and __lt__ operators as follow: a) sum = obj1 + obj2 sets sum. var1 to be obj1. var1 + obj2. var1, and sum. var2 to be obj1.var2 + obj2. var2b) obj1 == obj2 only if obj1. var1 == obj2. var1 and obj1. var2 == obj2. var2c) obj1 < obj2 only if obj1. var1 + obj1. var2 < obj2. var1 + obj2. var2

Write the source code of enum CrewType.
in kotlin, Use this Employee class data class Employee(val name: String, val wage: Double, val hours: Double) and this list of Employees: val l: List = listOf(Employee("Bob", 34.33, 42.0), Employee ("Cathy", 27.33, 15.25), Employee("Carlos", 46.99, 38.75), Employee("Tomas", 49.66,28.45), Employee("Xavier", 34.56, 11.5)) Write a function called raise which takes a list of Employees and a Double and returns a list of Employees like the original but with each having received a raise, with the Double representing the percentage raise. For example, if an employee's wage was $20 per hour and the Double is .15 (that is, 15%), her new wage will be $23 per hour. Don't change the Employees; create and return a list of new Employee objects with the new wages. Use Kotlin's map() function.
Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Planet code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information for each planet: Name, distance from sun, radius, and mass. section 10.4
Given the following custom class (myClass , which of the following statements are TRUE? Select all that apply. class myClass: def _init_(self, code, name): self.code = code self.name = name self.roster = [] def enrol(self, 1st: list[str]) -> None: Add each element of to the roster once. for item in lst: if item not in self.roster: self.roster.append (1st) The attribute roster cannot be defined, since it's not a parameter of the initializer. O The method enrol is correct. The method enrol is incorrect because it doesn't properly add elements to the roster. The method enrol is incorrect because it doesn't properly ignore duplicate string elements. The method enrol is incorrect because it doesn't return anything. The initializer is incorrect as it creates more attributes than are passed. The command print(c.roster) prints the list roster, where c is an instance of myClass. The command print(c.roster) prints a memory address, as _repr_ or _str__ aren't defined.
In Kotlin, use this Employee class Use this Employee class data class Employee(val name: String, val wage: Double, val hours: Double) and this list of Employees: val l: List = listOf(Employee("Bob", 34.33, 42.0), Employee ("Cathy", 27.33, 15.25), Employee("Carlos", 46.99, 38.75), Employee("Tomas", 49.66,28.45), Employee("Xavier", 34.56, 11.5)) Write a function called formatPaycheck that takes a Pair and returns a String. formatPaycheck should use the two parts of the Pair to put together and return a String like this, with the paycheck amount shown to two digits past the decimal point: Pay to the order of Cathy $359.47 Use raise() to raise all the Employees' pay by 15%. Then use map with the payroll and formatPaycheck functions to get a list of the paychecks in the format shown above. Print the result. The output should look like this: [Pay to the order of Bob $1077.79, Pay to the order of Cathy $359.47, Pay to the order of Carlos $1361.09, Pay to the order of Tomas $1056.09,…
