Use class by calling random name Python

I get error printing result.age Why? How I can fix it?

import random

names = ['Bob', 'Robert', 'Tom']
result = random.choices(names, weights=[5, 10, 12], k=random.randint(1, 3))
print(result)

class People:
    def __init__(self, age, city):
        self.age = age
        self.city = city
Bob = People('23', 'NewYork')
Robert = People('73', 'Boston')
Tom = People('43', 'Oslo')

print(result.age)

Thx for any help.
