Speaking of which, how is this parsed? f"{'\n'}" If escape-handling is done first, the expression is a string literal holding an actual newline character (normally illegal), rather than an escape sequence which resolves to a newline character.
It's illegal.
If that one somehow works, how about this? f"{r'\n'}"
Also illegal.
I guess you'd have to write one of these: f"{'\\n'}" f"{'''\n''')" rf"{'\n'}"
Modulo the typo in the second one, these all result in the same code:
dis.dis(lambda: f"{'\\n'}") 1 0 LOAD_CONST 1 ('\n') 2 FORMAT_VALUE 0 4 RETURN_VALUE f"{'\\n'}" '\n'
