PyDev 7.3.0 warns uselessly about iterable unpacking with Python 3.7

Question

Stop editing just to gain few points of reputations and not helping, thanks

First of all, it does not bother the compilation of my code. The command (base) user@machine:~$ python script.py works perfectly and gives what I expect.
What is bothering is during the edition of the code in Eclipse. While the following line is acceptable and compiled well with Python 3.7 a,b,c = *func_returns_2_things(),func_returns_1_thing().
What Eclipse warns : Encountered "*" at line X, column Y. Was expecting one of: "("..., "{"... #and so on
Of course, I tried this [*func_returns_2_things(),func_returns_1_thing()] but it still warns an error: Expected:].
Besides I shouldn't not say "warns" because warning are mentioned with a yellow triangle, and here this is clearly a red circle with red cross in (if you know what I mean).

What can I do to stop this useless warning in my Eclipse edition ?

Notes: def func_returns_2_things(): return 1,2 ; def func_returns_1_thing(): return 4

PyDev and Eclipse both have newer versions. You should try updating to them first. — nitind, Apr 13 '21 at 18:45
@nitind I clicked "Help" in menu, then clicked "check for updates" and accepted the updates. It updated and there is still this problem occurring. — AvyWam, Apr 13 '21 at 18:49
@nitind now that's updated it don't work anymore: `No editor descriptor for id org.python.pydev.editor.PythonEditor` while PyDev is installed... — AvyWam, Apr 13 '21 at 20:21
@nitind I would prefer to know that before. That's super easy to do on Ubuntu, haha. — AvyWam, Apr 13 '21 at 20:26
@nitind update to Java 11 in order to use the last version of Pydev keeps the error: `Encountered "*"`. — AvyWam, Apr 13 '21 at 21:55

I think that the problem is probably that your project is configured to validate the syntax for a different version of Python.

i.e.: In the project properties, PyDev - Interpreter/Grammar you probably have an older version of Python selected (either in Grammar version or Additional syntax validation).

See: https://www.pydev.org/manual_101_project_conf2.html for more details.

You were right. First, I checked in the menu `Window` -> `Preferences` -> `Pydev` -> `Interpreters` -> `Python interpreters`. By default it was selected a version in the root `/usr/bin/python` that I do not use and changed to the desired one `/path/anaconda/bin/python3.7`. Second, as you told, with a Right Click on the project, then clicking `Properties` - > `Pydev interpreter/grammar` I can change as I want which version to use: the default selected previously in First or another. Thank you! – AvyWam Apr 16 '21 at 10:20
