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. Far 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. Programming Style Requirements. Variable names-use meaningful variable names such as total caxes 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

I have program 7 wrote can you help me with program 8?
Transcribed Image Text:### Programming Exercises
#### 7. Random Number File Writer
Create a program that writes a series of random numbers to a file. Each number should range from 1 to 500. The program should allow the user to specify how many random numbers the file will contain.
#### 8. Random Number File Reader
This exercise requires the completion of Exercise 7. It involves writing a program that reads random numbers from the file, displaying:
- The total of the numbers.
- The number of random numbers read from the file.
Additionally, Problem 8 should calculate and display the average of the random numbers.
### Exception Handling
Both programs must incorporate `try` and `except` clauses to handle `IOError`, `ValueError`, and other unspecified error exceptions. Test your programs for invalid scenarios, such as reading a non-existent file or corrupted data.
### Programming Style Requirements
- **Variable Names**: Use descriptive names, e.g., `total_sales` instead of `num_cookies`.
- **Function Names**: Use meaningful verbs, e.g., `display_taxes`.
- **Named Constants**: Include constants for unchangeable values, e.g., `RECIPE_SUGAR = 1.5`.
