Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class. Class name BankAccount Attributes _balance float _pin integer Methods init () get_pin() check pin () deposit () withdraw () get_balance () The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin () should return the pin. check_pin (pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit (amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw (amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance () should return the current balance.…
14.23 LAB: Dean's list Students make the Dean's list if their GPA is 3.5 or higher. Complete the Course class by implementing the get_deans_list() instance method, which returns a list of students with a GPA of 3.5 or higher. The file main.py contains: . The main function for testing the program. Class Course represents a course, which contains a list of student objects as a course roster. (Type your code in here.) • Class Student represents a classroom student, which has three attributes: first name, last name, and GPA. (Hint: get_gpa() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Dean's list: Henry Nguyen (GPA: 3.5) Sonya King (GPA: 3.9)
Car Class Project The car classwill havethe following attributes: •year: an integer that holds the car's model year •model: a string that holds the make of the car •make: a string that holds the model of the car •speed: an integer that holds the car's current speed Your class should contain thefollowing: A docstring that briefly describes the class and lists the attributes. The docstring will serve as the documentation for your class. •A constructor (__init__ method) that takes the car's year model and make as optional arguments. The constructor will set the value of the speed attribute to 0.•An __str__ method that returns the car's year model and makein a string. •To test your class, create acar object and use the print function to verify that the constructor and __str__ methodsare working correctly. •An accessor method which returns the value stored in the speed instance variable. Call this method getSpeed(). •A modifier method called accelerate() which adds 5 to the speed variable…

Lab 2 – Designing a class This lab requires you to think about the steps that take place in a program by writing pseudocode. Read the following program prior to completing the lab. Design a class named Computer that holds the make, model, and amount of memory of a computer. Include methods to set the values for each data field, and include a method that displays all the values for each field. For the programming problem, create the pseudocode that defines the class and enter it below. Enter pseudocode here
StockList Class • This class will contain the methods necessary to display various information about the stock data. • This class shall be a subclass of ArrayList. • This class shall not contain any data fields. (You don't need them for this class if done correctly). • This class shall have a default constructor with no parameters. o No other constructors are allowed. • This class shall have the following public, non-static, methods: • printAllStocks: This method shall take no parameters and return nothing. ▪ This method should print each stock in the StockList to an output file. ▪ NOTE: This method shall NOT print the data to the console. The output file shall be called all_stock_data.txt. The data should be printed in a nice and easy to read format. o displayFirstTenStocks: This method shall take no parameters and return nothing. ▪ This method should display only the first 10 stocks in the StockList in a nice and easy to read format. ▪ This method should display the data in the…
Scores Class Write a class named Scores which should have the following attribute: • _scores (a list to hold test scores, 0 - 100. Initially empty. ) The Scores class should have an _init__ method that creates the _scores attribute. It should also have the following methods: • add_score: this method adds a score to the __scores list. It accepts a single score as it's' only argument. • get_average: this method accepts no arguments. If _scores is empty, this method returns -1. Otherwise, it returns the average of all scores in _scores. • get_high_score: this method accepts no arguments. if scores is empty, this method returns -1. Otherwise, it returns the highest score in __scores. • get_low_score: this method accepts no arguments. if scores is empty, this method returns -1. Otherwise, it returns the lowest score in scores. • _str_: This method returns a string similar to the following (assuming the _scores contains 89, 77, 93): Once you have written the class, write a program that…

In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.
