The internet enables people to network, join a cause, take a poll, etc. Your program will prompt the user for a description of a poll to be taken and then prompt 5 users for a response of 1-10 (1 being a 'poor' response; 10 being the 'best' response).Your program does not have to validate that the user entered 1-10. We'll do that type of checking later.Your program must use a string data type to store the poll description and a Python list data type to save the integer responses of the 5 user responses.Your output should list all the responses stored in the list, the highest given response, the lowest given response and the average of the 5 responses.
