hi
i need solution for this
Each account should have a constant, unique id. Id numbers should start from 1000 and increment by 5. The ACCOUNT_ID attribute should be initialised when the account object is created. The id should be generated internally within the class, it should not be passed in as an argument

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…arrow_forwardCreational Patternarrow_forward
