A module has been imported but is not used anywhere in the file. The module should either be used or the import should be removed.
In this example, it is likely that
namedtuple was going to be used instead of a regular
namedtuple was never used. It should be removed.
from collections import namedtuple my_tuple = ('Grant', 'McConnaughey', 25)
my_tuple = ('Grant', 'McConnaughey', 25)
