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…

Please written by computer source Unit 4 - Lab – Individual Retirement Account Calculation Assignment An Individual Retirement Account (IRA) is a special bank / brokerage account that a person can use to save money for retirement. An individual can put up to $5,500 per year tax free and the money grows tax free until the person is ready to retire. The tax rules related to IRA’s are complex, but for this assignment, we’ll assume that the person puts in the same amount of money every year (up to $5,500) and the money grows at a constant interest rate. Write a Flowgorithm program that asks the user to input an annual IRA contribution (in dollars), and interest rate (percent), and a time period (years). Calculate the value of the IRA every year for the duration of the time period provided by the user. Be sure and provide user friendly prompts. Include a comment at the beginning of the program with your name, date, and a short description of the program.

Command Program Create a program that allows you to view and edit the sales amounts for each month of the current year. This program is required to use commands add, view, totals, edit, and exit. The program should use a list to store the sales data for each month with the three-letter abbreviation for the month (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, and Dec) to use as the key for each item. When the program starts, it should read the sales data inserted from the user. If the user edits the sales data, the program should edit the data If the user selects total, then the program should calculate the total sales and average monthly sales. Use functions to view sales, edit sales, calculate total, and calculate average. Please use all commands, and thank you in advance.
The Problems - contains only problems from the last 2 contests Separate Un-Attempted, Attempted and All cards Problem Difficulty Rating - The Featured drop-down menu has different difficulty ranges so you can try problems that best suit your experience. Popular topics and brands Like most users, Chef didn't know that he could add problems to his personal to-do list by clicking the magic "+" symbol in the upper right corner of each problem page. But once he found out about it, he went crazy and added a lot of problems to his to-do list without looking at their difficulty rating. Rajesh is a beginner and ideally should only try to solve problems strictly below 10001000. Given the difficulty rating list of problems in Chef's to-do list, please help him determine how many of these problems Chef should remove from his to-do list so he is left with only problems with a difficulty rating of less than 10001000. Note: Please answer the question in Python only: Input 1 4 999 1000 1001 1002…
