False positive for E0602?

[KommuSoft]

Bug description

If I run pylint on the following:

item = (1,4,2,5)
for item in item:
    print(item)

(I agree this is very bad practice, I encountered this while cleaning up an ugly codebase)

I get the following error:

file.py:2:12: E0602: Undefined variable 'item' (undefined-variable)

But this makes not much sense, since the variable is defined. Likely pylint reasons that since for assign a value to item, at the time the item is read as source of items, item is not defined, but it is.

Now it is definitely a good idea to generate a warning for this, but the variable is defined, so I think this is a false positive for E0602?

Command used
