Indeed, as Andre mentions your example is different because in you case the 
call is interpreted as a generator comprehension, not as a function call.

Andre Roberge  added the comment:

Your example is different than the one in the documentation (What's new).

>>> (x, x for x in range(7))  # Your example
  File "", line 1
(x, x for x in range(7))
  ^^^
SyntaxError: invalid syntax

>>> foo(x, x for x in range(7))  # Example similar to the docs
  File "", line 1
foo(x, x for x in range(7))
   ^^^
SyntaxError: Generator expression must be parenthesized

>>> [x, x for x in range(7)]  # Yet a different example
  File "", line 1
[x, x for x in range(7)]
 
SyntaxError: did you forget parentheses around the comprehension target?

[issue44447] Syntax Error not as detailed as shown

[Eesa Ibrahim Khokhar]

New submission from Eesa Ibrahim Khokhar :

I was testing the new features for python 3.10 beta 3, and noticed the errors 
were not as detailed as shown in the docs.

I have an image below:


In the docs, it was said that the entire generator statement would be pointed 
out by carets. However, it only pointed out 'for', and the error was not as 
detailed as shown in the docs.
