I found a new error specific to 3.13.

cpython/Parser/lexer/lexer.c

Lines 1107 to 1110 in fc1c644

if (the_current_tok->f_string_quote == quote &&
the_current_tok->f_string_quote_size == quote_size) {
return MAKE_TOKEN(_PyTokenizer_syntaxerror(tok, "f-string: expecting '}'", start));
} 

-      return MAKE_TOKEN(_PyTokenizer_syntaxerror(tok, "f-string: expecting '}'", start));
+      return MAKE_TOKEN(_PyTokenizer_syntaxerror(tok, "f-string: expecting '}'"));

This is fixed by 6020260 in 3.14.

Hum. Your PR description described a bug which is not fixed by the PR. It's misleading.

Do you plan to integrate a fix for return MAKE_TOKEN(_PyTokenizer_syntaxerror(tok, "f-string: expecting '}'", start)); in this PR?

I’m not sure if I should fix it within this PR or address it in a separate one. What do you think?

You can update this PR to fix also the _PyTokenizer_syntaxerror() issue.
