The user may add more data whenever they want. The print also allows the user to display the data and to print the statistics. The data is store in a list. It’s easier if you make the list global so that other functions can access it. You should have the following functions: · add_from_file() – prompts the user for a file and add the data from it. · add_by_hand() – prompts the user to enter data until user type a negative number. · print_stats() – print the stats (min, max, mean, sum). You may use the built-in functions. Handling errors such as whether the input file exist is extra credit. To print a 10-column table, you can use the code below: for i in range(len(data)): print(f"{data[i]:3}", end="") if (i+1)%10==0: print() print() Sample run: Choose an action 1) add data from a file 2) add data by hand 3) print stats 4)…
