- Phyton: Program 6: Write a program that allows the user to add data from files or by hand. 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)…arrow_forwardreads an external character file and passes it to a list variable.

The function then calls is_valid_index() to verify that the provided index idx is a valid positive index that can access an element from info_list. On success, the function saves the item from info_list and returns it after it is deleted from info_list. returns: If info_list is empty, return 0. If is_valid_index() returns False, return -1.
