Description

Closes #9109

[jacobtylerwalls]

Thanks for the patch!

Based on the test results, you'll notice you'll need to adjust the logic of #4500 to make it a little dumber (and therefore more like the original intent of #2999).

I'm on mobile si I can't link the specific code but the message is raised in the add_message function, the message is dynamic and the argument given to add_message used in %s later is what need to be modified.

Thank you for your contribution, it looks promising, do you mind adding the functional tests from #8577

a = [[1, 2], [3, 4]]
b = [(x, y) for x, y in a]  # flagged as unnecessary-comprehension

And #9109:

#pylint: disable=missing-module-docstring
a = [1, 2, 3]
b = [x for x in a]
b[0] = 0
print(a) # [1, 2, 3]

in tests/functional/u/unnecessary/unnecessary_comprehension.py, please ?

[Pierre-Sassoulas]

Also a bug / or false positive changelog fragment would be nice for this one.

in the unnecessary_comprehension.py on line 5 it can be use for 9109 and
for 8577 ' [(x, y) for x, y in iterable] # [unnecessary-comprehension] ' is this good
