I did this in IDLE 3.7.5, and it gives a syntax error on the last line.
This is correct, because the f-string is in error. Between the curly
braces there should be an expression, possibly followed by a conversion
(!...) and/or a format specification (:...). {i=} is not a correct
expression. When you remove the »f«, it becomes a normal string, where
the {} don't have a special meaning.
