Complete the Error, SyntaxError, and ZeroDivisionError classes such that they create the correct messages when called.

• The SyntaxError and ZeroDivisionError classes inherit from the Error class and add functionality that is unique to those particular errors. Their code is partially implemented for you.
• The add_code method adds a new helpful message to your error, while the write method should print the output that you see when an error is raised.
• You can access the parent class methods using the super() function

    >>> err1 = Error(12, "error.py")
    >>> err1.write()
    'error.py:12'

    def __init__(self, line, file):
        "*** YOUR CODE HERE ***"

    def write(self):
