Make a realistic sample dictionary of people in Python. The key should be a random 16-character hex string, and the value should be a dictionary of: `names` (a tuple), `surname`, `gender` (an enum containing `gender.FEMALE`, `gender.MALE`, and `gender.OTHER`), and phone number (all with the 555-01 prefix for fictitious numbers). 5 people should suffice for now.
Here is a realistic sample dictionary in Python of 5 people according to your specifications:

```py
from enum import Enum

Gender = Enum('Gender', ['FEMALE', 'MALE', 'OTHER'])
people = {
    'c998939787fc3d5c': {
        'names': ('Jordan',),
        'surname': 'Peters',
        'gender': Gender.MALE,
        'phone_number': '555-0183',
    },
    'b747c9143ac84eb0': {
        'names': ('Juniper', 'Junie'),
        'surname': 'Richardson',
        'gender': Gender.FEMALE,
        'phone_number': '555-0118',
    },
    '6747bdc902e73f97': {
        'names': ('Mary',),
        'surname': 'Windsor',
        'gender': Gender.FEMALE,
        'phone_number': '555-0180',
    },
    '5e78b599993dd030': {
        'names': ('Reyna',),
        'surname': 'Keeble',
        'gender': Gender.FEMALE,
        'phone_number': '555-0193',
    },
    '61fdbfcf69c2f76f': {
        'names': ('Leonard', 'Lenny'),
        'surname': 'Brown',
        'gender': Gender.MALE,
        'phone_number': '555-0109',
    },
}
```

Bear in mind that I gave the key `surname` a type of `str`.
create a web server that serves this as json
Here is an example of a simple web server that serves the sample dictionary of people as JSON using the Flask library in Python:

from flask import Flask, jsonify
from enum import Enum

app = Flask(__name__)

Gender = Enum('Gender', ['FEMALE', 'MALE', 'OTHER'])
people = {
    'c998939787fc3d5c': {
        'names': ('Jordan',),
        'surname': 'Peters',
        'gender': Gender.MALE,
        'phone_number': '555-0183',
    },
    'b747c9143ac84eb0': {
        'names': ('Juniper', 'Junie'),
        'surname': 'Richardson',
        'gender': Gender.FEMALE,
        'phone_number': '555-0118',
    },
    '6747bdc902e73f97': {
        'names': ('Mary',),
        'surname': 'Windsor',
        'gender': Gender.FEMALE,
        'phone_number': '555-0180',
    },
    '5e78b599993dd030': {
        'names': ('Reyna',),
        'surname': 'Keeble',
        'gender': Gender.FEMALE,
        'phone_number': '555-0193',
    },
    '61fdbfcf69c2f76f': {
        'names': ('Leonard', 'Lenny'),
        'surname': 'Brown',
        'gender': Gender.MALE,
        'phone_number': '555-0109',
    },
}

@app.route(/)
def index():
    return jsonify(people)

if __name__ == __main__:
    app.run()

To run the server, save the code in a file with a .py extension and run it using the command python <filename>.py. You can then access the JSON data by visiting http://localhost:5000/ in a web browser or using a tool such as curl.
