__enter__ and __exit__ - methods extend the capability of the class to be used using a with statement same way the context manager works.

class Host:

    def __init__(self, ipaddress, username, password):

        print(f"IN __init__")

        self.ipaddress = ipaddress

        self.username = username

        self.password = password

    def __str__(self):

        return f"Host-{self.ipaddress}/{self.username}:{self.password}"

    def method_x(self):

        """

"""

        print(f"###IN method_x####")

    def __del__(self):

        """

dereference the object etc.

"""

        print(f"IN __del__")

    def __enter__(self):

        print("IN __enter__")

            return self

    def __exit__(self, type, value, traceback):
