sure! i'd be happy to provide a tutorial on creating a rest api using python flask that accepts query parameters in a get request. query parameters allow clients to filter, sort, or limit the data returned by the api.

here's a step-by-step tutorial with code examples:

step 1: install flask
make sure you have flask installed. you can install it using pip:

step 2: create a flask app
create a new python file, for example, `app.py`, and import flask:

step 3: create a route with query parameters
define a route that accepts query parameters. in this example, we'll create an endpoint `/books` that accepts `author` and `category` query parameters:

step 4: run the flask app
add the following code to the end of your `app.py` file to run the flask app:

step 5: test the api
start the flask app by running `python app.py`. you can now make get requests to `http://localhost:5000/books` with query parameters:

`http://localhost:5000/books` (returns all books)
`http://localhost:5000/books?author=author a` (returns books by author a)
`http://localhost:5000/books?category=fantasy` (returns books in the fantasy category)
`http://localhost:5000/books?author=author a&category=sci-fi` (returns books by author a in the sci-fi category)

that's it! you've created a flask rest api that accepts query parameters in get requests. feel free to expand on this example by adding more routes and handling additional query parameters.
