Modify Both python programs to handle IoError, ValueError and unspecified error expectations using Try and Except clauses
```python def readRandomNumbers(): numbers = list() with open("random_numbers.txt", "r") as file: for line in file: numbers.append(int(line.rstrip())) file.close() return numbers def displayData(numbers): print("The total of the numbers: %d" % sum(numbers)) print("The numbers of random numbers read from the file: %d" % len(numbers)) if __name__ == "__main__": randomNumbers = readRandomNumbers() displayData(randomNumbers) ``` **Explanation:** This Python script is designed to read numbers from a file and display some statistics about them. Here is a breakdown of the code: - `readRandomNumbers()`: This function reads a file named `random_numbers.txt`. It assumes each line in this file contains a single integer. It opens the file, reads each line, strips any whitespace, converts it to an integer, and appends it to a list called `numbers`. After reading all lines, it returns the list of numbers. - `displayData(numbers)`: This function takes a list of numbers as input and prints out two pieces of information: the sum of all the numbers in the list and the count of numbers read from the file. - The `if __name__ == "__main__":` block ensures that the `readRandomNumbers()` and `displayData()` functions are called only when this script is executed directly, not when imported as a module.

```python from random import randint def generate_number(): return randint(1, 500) def write_to_file(count): with open("random numbers.txt", "w") as file: for i in range(count): num = str(generate_number()) file.write(num + "\n") file.close() if __name__ == "__main__": count = int(input("Enter Number of random numbers to generate: ")) write_to_file(count) print("Written %d random numbers to file \"random numbers.txt\"." % count) ``` **Explanation:** This Python script generates a specified number of random numbers between 1 and 500 and writes them to a file named "random numbers.txt". Here's a breakdown of its components: 1. **Import Statement:** - `from random import randint`: Imports the `randint` function from the `random` module, which generates random integers. 2. **Function Definitions:** - `generate_number()`: Returns a random number between 1 and 500. - `write_to_file(count)`: Takes an integer `count` and writes `count` random numbers to "random numbers.txt", one per line. 3. **Main Execution Block:** - Checks if the script is being executed directly. - Prompts the user for input to determine how many random numbers to generate. - Calls `write_to_file(count)` to generate and save the numbers. - Prints a confirmation message with the total numbers written to the file.
