Define and test a function myrange. this function should behave like python’s standard range function, with the required and optional arguments. do not use the range function in your implementation! (hints: study python’s on range to determine the names, positions, and what to do with your function’s parameters. use a default value of none for the two optional parameters. if these parameters both equal none, then the function has been called with just the stop value. if just the third parameter equals none, then the function has been called with a start value as well. thus, the first part of the function’s code establishes what the values of the parameters are or should be. the rest of the code uses those values to build a list by counting up or down.)

Anew author is in the process of negotiating a contract for a new romance novel. the publisher is offering three options. in the first option, the author is paid $5,000 upon delivery of the final manuscript and $20,000 when the novel is published. in the second option, the author is paid 12.5% of the net price of the novel for each copy of the novel sold. in the third option, the author is paid 10% of the net price for the first 4,000 copies sold, and 14% of the net price for the copies sold over 4,000. the author has some idea about the number of copies that will be sold and would like to have an estimate of the royal- ties generated under each option. write a program that prompts the author to enter the net price of each copy of the novel and the estimated number of copies that will be sold. the program then outputs he royalties under each option and the best option the author could choose. (use appropriate named constants to store the special values such as royalty rates and fixed royalties.
