Using None as default makes it optional.

To make 'q' required, use Query(...). Other defaults make it optional.

Fill both blanks to declare two required query parameters: 'name' (str) and 'age' (int).

FastAPI

from fastapi import FastAPI, Query

FastAPI

from fastapi import FastAPI, Query

app = FastAPI()

@app.get("/items/")
