fastapi type Schedule add delete select update restapi

FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.6+ based on standard Python type hints. It provides an easy-to-use interface for creating RESTful APIs with minimal boilerplate code.

To create a RESTful API for a Schedule, you would typically define the following endpoints:

1. Add: HTTP POST request to add a new schedule item.
2. Delete: HTTP DELETE request to delete an existing schedule item.
3. Select: HTTP GET request to retrieve a list of all schedule items or a single schedule item by ID.
4. Update: HTTP PUT request to update an existing schedule item.

Here is an example implementation of these endpoints using FastAPI:

from typing import List
from fastapi import FastAPI

app = FastAPI()

class Schedule:
    def __init__(self, id: int, title: str, description: str, date: str):
        self.id = id
        self.title = title
        self.description = description
        self.date = date

# Mock data
schedule_items = [
    Schedule(1, "Meeting", "Weekly team meeting", "2022-01-05T10:00:00"),
    Schedule(2, "Lunch", "Lunch with clients", "2022-01-06T12:30:00"),
    Schedule(3, "Conference", "Python conference", "2022-01-10T09:00:00"),
]

@app.post("/schedule")
def add_schedule_item(schedule: Schedule):
    """
    Add a new schedule item.
    """
    schedule_items.append(schedule)
    return {"message": "Schedule item added successfully."}

@app.delete("/schedule/{schedule_id}")
def delete_schedule_item(schedule_id: int):
    """
    Delete an existing schedule item by ID.
    """
    for i, schedule in enumerate(schedule_items):
        if schedule.id == schedule_id:
            del schedule_items[i]
            return {"message": "Schedule item deleted successfully."}
    return {"error": "Schedule item not found."}

@app.get("/schedule")
def get_all_schedule_items() -> List[Schedule]:
    """
    Retrieve a list of all schedule items.
    """
    return schedule_items

@app.get("/schedule/{schedule_id}")
def get_schedule_item(schedule_id: int) -> Schedule:
    """
    Retrieve a single schedule item by ID.
    """
    for schedule in schedule_items:
        if schedule.id == schedule_id:
            return schedule
    return {"error": "Schedule item not found."}

@app.put("/schedule/{schedule_id}")
def update_schedule_item(schedule_id: int, schedule: Schedule):
    """
    Update an existing schedule item by ID.
    """
    for i, s in enumerate(schedule_items):
        if s.id == schedule_id:
            schedule_items[i] = schedule
            return {"message": "Schedule item updated successfully."}
    return {"error": "Schedule item not found."}

With this implementation, you can use HTTP requests to add, delete, select, and update schedule items via the API. For example, to add a new schedule item, you could send a POST request to http://localhost:8000/schedule with a JSON payload containing the schedule data:

{
    "id": 4,
    "title": "Training",
    "description": "Training session for new recruits",
    "date": "2022-01-15T14:00:00"
}

You could then use GET requests to retrieve the list of all schedule items or a single schedule item by ID, and PUT and DELETE requests to update or delete existing schedule items.
