paython programing question
Write a program that creates a list of N elements (Hint: use append() function), swaps the first and the last element and prints the list on the screen. N should be a dynamic number entered by the user.
Sample output:
How many numbers would you like to enter?: 5
Enter a number: 34
Enter a number: 67
Enter a number: 23
Enter a number: 90
Enter a number: 12
The list is: [12, 67,23, 90, 34]

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.
