Сheck if an element from a list is in another list that contains a namedtuple

[elnk]

Hello, i have this code:

def some_generator(some_args):
    Import = namedtuple("Import", ["module", "name", "alias"]) # "module", "name" and "alias" can be listed
...
    for n in node.names:
        yield Import(module, n.name.split('.'), n.asname)
...
files = list()
requirements = list()
...
for member in members:
    files.append(member)
...
for requirement in self.some_generator(some_args):
    requirements.append(requirement)
...

and then i need to check if an element from "files" is in "requirements" (module, name or alias)
how to implement it?
