How to parse list of models with Pydantic

Question

I use Pydantic to model the requests and responses to an API.

I defined a User class:

from pydantic import BaseModel

class User(BaseModel):
  name: str
  age: int

My API returns a list of users which I retrieve with requests and convert into a dict:

users = [{"name": "user1", "age": 15}, {"name": "user2", "age": 28}]

How can I convert this dict to a list of User instances?

My solution for now is

user_list = []
for user in users:
  user_list.append(User(**user))

I have another idea to simple this code if pydantic version below 1.2 that doesn't support parse_obj_as method.

user_list = []
for user in users:
  user_list.append(User(**user))

simple way

user_list = [User(**user) for user in users]

I just set in my models.py list of dict like this:

from django.db import models
from pydantic import BaseModel

class CustomList(BaseModel):
    data: list[dict]
