Docs: incorrect error message #116563
Description
Documentation
Part 8 of the Python tutorial contains the following example:
>>> while True print('Hello world')
File "<stdin>", line 1
while True print('Hello world')
^
SyntaxError: invalid syntaxAs tested on Python 3.12 and 3.13, the actual error highlight would be:
>>> while True print('Hello world')
File "<stdin>", line 1
while True print('Hello world')
^^^^^
SyntaxError: invalid syntaxhence the following description might be inaccurate as well:
The parser repeats the offending line and displays a little ‘arrow’ pointing at the earliest point in the line where the error was detected. The error is caused by (or at least detected at) the token preceding the arrow: in the example, the error is detected at the function print(), since a colon (':') is missing before it. File name and line number are printed so you know where to look in case the input came from a script.
I guess that @pablogsal as an expert in a Python error messages might provide more data on current error handling :)

The change happened with the new parser in 3.10. I will change the example and change the text to 'one or more'. The rest is still the same for me also. Thank you for linking to spot of the foul.
