[New-bugs-announce] [issue45801] Incorrect "Perhaps you forgot a comma" hint

[Andre Roberge]

New submission from Andre Roberge <andre.roberge at gmail.com>:

Python 3.10 and 3.11:

>>> sum[i for i in [1, 2, 3] if i%2==0]
  File "<stdin>", line 1
    sum[i for i in [1, 2, 3] if i%2==0]
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: invalid syntax. Perhaps you forgot a comma?

Furthermore, I don't find that highlighting the entire statement (or parts of it, if we use print(sum[...]) is very useful in attempting to find the source of the error.

In previous versions, we would get the following:

>>> sum[i for i in [1, 2, 3] if i%2==0]
  File "<stdin>", line 1
    sum[i for i in [1, 2, 3] if i%2==0]
          ^
SyntaxError: invalid syntax
