Every new account gets everyone's tags

Accounts start from shared DEFAULTS. After a few sign-ups, support notices that each new account shows the tags of every earlier account, and switching SMS on for one person switched it on for others. Fix new_account so every account owns its own settings and DEFAULTS never changes.

Functionnew_account(user_id, tags)

Returnsa new dictionary: user_id, notify ({"email": True, "sms": False}) and tags (the given tags, in order)

Rulestwo accounts never share their notify dictionary or their tags list, with each other, with DEFAULTS or with the list passed in

KeepDEFAULTS and the function's name and result; only the bug should change

Examples

callnew_account('u-ana', ['beta'])returns{'user_id': 'u-ana', 'notify': {'email': True, 'sms': False}, 'tags': ['beta']}

callnew_account('u-ben', ['vip', 'eu'])returns{'user_id': 'u-ben', 'notify': {'email': True, 'sms': False}, 'tags': ['vip', 'eu']}

callnew_account('u-cai', [])returns{'user_id': 'u-cai', 'notify': {'email': True, 'sms': False}, 'tags': []}
