New submission from Terry J. Reedy <[email protected]>:
Document that SyntaxError args[1] is a tuple of the other attributes and how
the meaning of the attributes is adjusted when the syntax error is in an
f-string field replacement expression. Also add compile() to the list of
builtins that can raise SyntaxError.
PR to follow immediately. I wrote most of the text so that it works for 3.9
and 3.10+, with the new end info. In the example, the main part of the message
changed from "invalid syntax" to "invalid syntax. Perhaps you forgot a comma?".
I hid that with '...' but each could be given in the respective versions.
args[1] changes from "('', 1, 4, '(a b)\n')" to "('', 1, 2, '(a b)\n', 1, 5)"
and that will have to be changed in a 3.9 backport.
Spinoff from #43705. I will create a separate issue for using this information
in IDLE.
