Agroup of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers, as defined in section 5.4. define these functions in a module named stats. py. also include a function named mean, which computes the average of a set of numbers. each function should expect a list of numbers as an argument and return a single number. each function should return 0 if the list is empty. include a main function that tests the three statistical functions. ask users to enter the list of numbers, and then choose which function to apply to those numbers. after the single number is returned from the correct function, display to the user the list of numbers, the function selected and the answer in a format that is easy to understand.
