W0640 cell-var-from-loop false positive in Generator Comprehension of functions #10055

Open nhdsd opened 3 weeks ago

nhdsd commented 3 weeks ago

Bug description

test = (lambda : print(i) for i in range(10))
for call in test:
    call()

Command used

pylint -sn --disable=C0114 test.py

Pylint output

test.py:1:23: W0640: Cell variable i defined in loop (cell-var-from-loop)

Expected behavior

No W0640, since the generator do generate functions as expected instead of generating print(9) for 10 times.
