# Write a Python program that reads the data from the file, calculates the average age of the people in the file, and writes the result to another file called output.txt$.$

# Here are the requirements:

# $1)$ If the data.txt file does not exist or cannot be opened, the program should catch the exception and print an error message to the console.

# $2)$ If the data in the file is not in the correct format $($i$.$e$.,$ if there are missing fields or fields are not in the correct order$),$ the program should catch the exception and print an error message to the console.

# $3)$ If the program is unable to calculate the average age $($e$.$g$.,$ if there are no people in the file$),$ the program should catch the exception and print an error message to the console.

# $4)$ The output should be written to the output.txt file in the following format: "The average age is XX$",$ where XX is the average age rounded to the nearest integer.
