+# == INSTRUCTIONS ==
+#
+# Purpose: Manage a user's (valid) passwords
+#
+# Methods:
+#   1. Name: __init__
+#      Arguments: none
+#   2. Name: add
+#      Purpose: add a password for a service IF it is valid, otherwise do nothing
+#      Arguments: one string representing a service name,
+#                 one string representing a password
+#      Returns: None
+#   3. Name: get_for_service
+#      Arguments: one string representing a service name
+#      Returns: the password for the given service, or None if none exists
+#   4. Name: list_services
+#      Arguments: none
+#      Returns: a list of all the services for which the user has a password
+#
+# A reminder of the validity rules:
+#   1. A password must be at least 8 characters long
+#   2. A password must contain at least one of each of the following:
+#       - It must be longer than 7 characters (8 is fine)
+#       - It must contain at least one of the following special characters:
+#         `!`, `@`, `$`, `%` or `&`
+#
+# We recommend that you store the passwords in a dictionary, where the keys are
+# the service names and the values are the passwords.
+#
+# Example usage:
+#   > password_manager = PasswordManager()
+#   > password_manager.add('gmail', '12ab5!678')   # Valid password
+#   > password_manager.add('facebook', '$abc1234') # Valid password
+#   > password_manager.add('twitter', '12345678')  # Invalid password, so ignored
+#   > password_manager.get_for_service('facebook')
+#   '$abc1234'
+#   > password_manager.get_for_service('not_real')
+#   None
+#   > password_manager.get_for_service('twitter')
+#   None
+#   > password_manager.list_services()
+#   ['gmail', 'facebook']
+#
+
+# == YOUR CODE ==
