Use single quotes inside a double-quoted f-string

…ng: expecting '}'`

@danielmlow Other that replacing " character with ', what other change is made? I'm not seeing it. Where is a [ or } character expected? Can you resubmit the PR without changing the quotes? That would make it easier to see the difference.

Oh I see now, I need to have single quotes inside a double-quoted f-string. Is that it?

Thanks for submitting the PR. I am merging.
