Challenge: Random Number File Writer and Reader

Description: In this programming challenge you are to create two Python programs. One program is to write a set of random numbers to a file. The second program is to read a set of random numbers from a file, counts how many were read, displays the random numbers, and displays the total count of random numbers.

Purpose: The purpose of this challenge is to provide experience generating random numbers, writing data to a file, reading data from a file, and obtaining and presenting information about the contents of the file.

Requirements:

In this programming challenge you are to create two Python programs: randomwrite.py andrandomread.py. One program, randomwrite.py, is to write a set of random numbers to a file. The second program, randomread.py, is to read a set of random numbers from a file, counts how many were read, displays the random numbers, and displays the total count of random numbers.

Random Number File Writer (randomwrite.py)

Create a program called randomwrite.py that writes a series of random integers to a file. The program is to request from the user how many random numbers to generate, the lower bound of the random numbers range, and the upper bound of the random numbers range. Each random integer value is to be on a separate line and is to be in the range of the inputted lower bound through the inputted upper bound. The file that the random numbers are written to is to be called randomnum.txt.

The user input is to be safe from crashes from invalid input. The user must enter a positive number for all required input (quantity of random numbers to generate, the lower bound of the random numbers range, and the upper bound of the random numbers range). If invalid input is received the user is to be given feedback and provided with the ability to enter a value again. A positive number is not zero and not negative. The program must not crash if an error occurs during a file operation. Use exception handling.

These are the same requirements for this program:

The program should accept user input for the quantity of random numbers to generate. The inputted number should be a positive integer. The program should accept user input for the lower bound of the random numbers range. The inputted number should be positive integer.

The program should accept user input for the upper bound of the random numbers range.

The inputted number should be positive integer. User input may not cause the program to crash. Exceptions from invalid user input must be handled gracefully. The user is to be given feedback about invalid input and given the opportunity to supply the input without needing to run the program again. The program should generate the user supplied amount of random integer numbers between the user supplied lower and upper bound range. The random integers should be written to a file called called randomnum.txt with each random integer being on a separate line.

Example:

How many random numbers do you want? 10 What is the lowest the random number should be: 1 What is the highest the random number should be: 10 The random numbers were written to randomnum.txt

Random Number File Reader (randomread.py) Create a program called randomread.py that reads a series of random numbers from a file called

randomnum.txt, counts how many there are, displays the random numbers, and displays the count.

The output to the user is to be labeled and nicely formatted. Prior to displaying the random numbers display the string List of random numbers in randomnum.txt: Each random number is to be displayed on a separate line. The count displayed to the user is to be preceded with the stringRandom number count:.

Example:

List of random numbers in randomnum.txt: 5 45 32

15

Random number count: 4

The program must not crash if an error occurs during a file operation. Use exception handling. For example, if randomread.py is run and there is no randomnum.txt file the program should handle the exception that occurs when attempting to open the file.
