"unused variable" does not appear when variable with same name in other file

[dpinol]

It looks like running vulture with confidence=100, is not reporting "unused variable" for function arguments named as other variables in other files. However, this does not happen if the "other variable" occurs in the same file.

kk.py

def kk():
    expr:int =3
 
def fn2(expr: int, expr2: int) -> None:
    pass
 
def qq():
    expr:int =3

kk()
fn2()
qq()

qq.py

def io():
    expr2=3
    return expr2

io()

See that it complain about expr argument in fn2 declaration, but does not complain about expr2.

vulture --min-confidence=10 kk.py qq.py
kk.py:3: unused variable 'expr' (60% confidence)
kk.py:5: unused variable 'expr' (100% confidence)
kk.py:9: unused variable 'expr' (60% confidence)

thanks
