Question

python program

Problem 3 (Taking User Input) Write a function called userGuess(n) that takes an integer n as an argument. This function should display n to the user and prompt them to enter the number num that is the largest power of 2 less than or equal to n. Have your function return the user's input num (it will be used in the next problem) Problem 4 (Making a Game) Finally, create a main() function for your program. The purpose of this function is to control the game-logic for a Power Quiz game. The steps of this game are as follows: • Generate a random integer n in the range [0,4096] • Ask the user to enter a number that is the largest power of 2 less than or equal to • Use your pow20 function to find the correct answer Check if user's answer is correct or not If so, add 1 to their score o If not, tell them the correct answer. Repeat these steps until the user types "stop" in place of a number. If the user types "stop", your program should print out their final score and finish.

Sample Output:

Welcome to Power Quiz Game What is the largest power of 2 that is less than or equal to 488?256 Correct! Score: 1 What is the largest power of 2 that is less than or equal to 1978?1024 Correct! Score: 2 What is the largest power of 2 that is less than or equal to 1722?1024 Correct! Score: 3 What is the largest power of 2 that is less than or equal to 164?250 Wrong! The correct answer is 128 What is the largest power of 2 that is less than or equal to 1700?1024 Correct! Score: 4 What is the largest power of 2 that is less than or equal to 3580?stop Your final score is 4
