7. Random Number File Writer Write a program that writes a series of random numbers to a file. Each random number should be in the range of 1 through 500. The application should let the user specify how many random numbers the file will hold. 8. Random Number File Reader This exercise assumes you have completed Programming Exercise 7, Random Number File Writer. Write another program that reads the random numbers from the file, displays the numbers, then displays the following data: • The total of the numbers The number of random numbers read from the file Problem 8 should also display the average of the random numbers. Exception Handling: Both programs should use Try and Except Clauses to handle IOError, ValueError, and unspecified error exceptions. Be sure to test your programs for invalid cases. For example, try running the second program to read the file when it doesn't exist or manually put bad data in the file and see what happens.

Question

Python program please if you can follow the instructers. it should be two files

  • Function comments – each function should begin with a comment explaining what the function does
  • Variable names – use meaningful variable names such as total_taxes or num_cookies.
  • Function names – use meaningful verb names for functions such as display_taxes.
  • Named constants – Use named constants for all number values that will not be changed in the program such as RECIPE_SUGAR = 1.5. See section 2.9 on Named Constants
## Exercise 7: Random Number File Writer Write a program that writes a series of random numbers to a file. Each random number should be in the range of 1 through 500. The application should let the user specify how many random numbers the file will hold. ## Exercise 8: Random Number File Reader This exercise assumes you have completed Programming Exercise 7, Random Number File Writer. Write another program that reads the random numbers from the file, displays the numbers, then displays the following data: - The total of the numbers - The number of random numbers read from the file **Additional Requirement:** Problem 8 should also display the average of the random numbers. ### Exception Handling: Both programs should use `Try` and `Except` clauses to handle `IOError`, `ValueError`, and unspecified error exceptions. Be sure to test your programs for invalid cases. For example, try running the second program to read a file when it doesn’t exist or manually put bad data in the file, and see what happens.

**Programming Style Requirements** - **Comments** – Begin your program with a comment that includes: a) your name, b) program status – either “Complete” or describe any incomplete or non-functioning part of your program c) A 1-3 line description of what the program does. - **Function comments** – Each function should begin with a comment explaining what the function does. - **Variable names** – Use meaningful variable names such as `total_taxes` or `num_cookies`. - **Function names** – Use meaningful verb names for functions such as `display_taxes`. - **Named constants** – Use named constants for all number values that will not be changed in the program, such as `RECIPE_SUGAR = 1.5`. See section 2.9 on Named Constants. You should have 2 program files to turn in.
