Question

Create Two programs in PYTHON for the following problem. Follow program style requirements.

You will create each program in the IDLE environment and save it as a python file
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
9. Exception Handing
Modify the program that you wrote for Exercise 6 so it handles the following exceptions:
• It should handle any 10Error exceptions that are raised when the file is opened and data
is read from it.
• It should handle any ValueError exceptions that are raised when the items that are read
from the file are converted to a number.

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.
Programming Style Requirements.
Comments-Begin your program with a comment that includes: a) your name, b)
program status- either "Complete" or describe any incompleteornon-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 numbervalues that will not be changed
in the program such as RECIPE_SUGAR = 1.5. See section 2.9 on Named Constants

Process by which instructions are given to a computer, software program, or application using code.
