IDLE does this when one runs code from the editor, because it
cannot/should not inject error messages into the editor buffer... AND it
replaces the ^ with red highlighting of the code pointed to. No
information is lost. Apparently, some beginners do not see the connection
between the SyntaxError box and the red highlighting. I think I should add
something to the box. Maybe 'The error was detected at the point of the red
highlighting.'

What a nuisance.

Or one can hit F5 to run the code or Alt-X to just check the syntax. A beginner
should do this every few lines, and it should be as easy as possible to check.
If one needs to ask about a syntax error, one can copy the code up and
including the highlighted part. Example:
"When I run this code in IDLE
def is_same(target, number:
if
I get a SyntaxError at 'if'."
If the OP had known to do this, the error might have been seen without posting.
