Python SyntaxError: f-string: unmatched '[' [duplicate]

Question

from fastapi import FastAPI
from fastapi.params import Body

app = FastAPI()

@app.post("/createposts")
def create_posts(payload: dict = Body(...)):
    print(payload)
    return {"new_post" : f"title {payload["title"]} content: {payload["content"]}"}

I'm trying to create an API with Fastapi, but every time I run the code I get this error related to the return statement: SyntaxError: f-string: unmatched '['

Thank you!

Please change

return {"new_post" : f"title {payload["title"]} content: {payload["content"]}"}

to

return {"new_post" : f"title {payload['title']} content: {payload['content']}"}

You can't have " quotes inside f"..."

The error says that after the first [ the string stops and breaks.
