Hey, I'm new to python so don't judge.

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:

I get a SyntaxError at 'if'."

If the OP had known to do this, the error might have been seen without
