Message 289501 - Python tracker
I'm adding another example here, where the lineno reporting is wrong:
from ast import parse
n = parse('''
def test():
return f"{a}"
''')
f = n.body[0].body[0].value.values[0]
n = f.value
print("name lineno", n.lineno)
In this example, the line number of the f-string inner variable is 1, while it should be 3.
As Mark Shannon said, this bug is affecting tools such as pyflakes and pylint.
