Fast API router group

In this article we will se a simple example of FastAPI router group. You cat crate router group for deferent model operation as bellow - 

from typing import Union

from fastapi import FastAPI, APIRouter

app = FastAPI()

todo_router = APIRouter(prefix="/todo")
@todo_router.get("/all") #URL: /todo/all
def todo_list():
    return todos

@todo_router.get("//position]") # URL: /todo/2
def todo_detail(todo_position: int):
    return todos[todo_position]

user_router = APIRouter(prefix="/user")
@user_router.get("/all") # URL: /user/all
def user_list():
    return ("users": users)
@user_router.get("/fposition)") # URL: /user/2
def user_detail(position: int):
    return ("position": users[position])
app.include_router(todo_router)
app.include_router(user_router)

Above example we see there is two router group called todo and user. First you need to create a APIRouter with prefix. Then you need to register group routes to created APIRouter. And finally you need to include APIRouter to main FastAPI app.
