Python3: f-string {} symbols screening

Question

i want to use f-string in my python code to write some json, but got a problem with screening {} symbols. What the correct way to screen lonely { } symbols? For example i want to write:

data = f'{[{{prod_id},{quantity},{size}}]}'

I cant get how to write it correctly, and basic python screening not working for me for some reason here.

What do you expect the string that comes out to look like? – JohnO May 27 '19 at 17:49 — JohnO, May 27 '19 at 17:49
{[{ 1,2,M }]} - this, for example – Andrej Vilenskij May 27 '19 at 17:51 — Andrej Vilenskij, May 27 '19 at 17:51

You can escape curly braces in f-strings by doubling them, e.g.

data = f"{{[{{{prod_id},{quantity},{size}}}]}}"
