PLZZZ PYTHON
Modify your code to print to a file instead of the console. make sure your program performs the following actions:
- Ask the user how many numbers they would like to enter
Then prompt the user to enter a number as many times as they requested.
Print the following to a file:
- How many numbers they entered
- The sum of the numbers
- The highest number
- The average of the numbers
Make sure to use a try-except block and include the finally block.
Describe the numbers you print. Do not just print numbers to the screen explain what each number represents.
(first picture is my code second picture is of a try-except- finally example that ive done as reference )
