_ variable should be ignored

[crsegerie]

_ is a convention for variable that are not used afterwards.

I'm not taking about _* variables, only _ variables

[nhoad]

So to be clear, you're saying functions like this?

def foo(a, b, c, _):
    return a + b + c

[crsegerie]

More like

def foo(a, b, c):
    _ = c
    return a + b 

_ should be ignored by default

[nhoad]

To make sure I understand, in this case we’d ignore the assignment to _, so then the c argument would be reported unused. Is that the behavior you’d want?

[FelipeLema]

I'm also in for def fn(a, b, c, _) not reporting error on _

if anything, report a warning if it's actually being used

[nhoad]

@FelipeLema that's a different request to what's being asked for here. What you're asking for is already supported - U101 is for unused arguments that start with an underscore, so you can simply start ignoring U101.

oh, I didn't know that... thanks for noting
