pyflakes does not know about lazy_import and may therefore emit distracting warnings - as noted in #30616 comment:8

We introduce a new method PythonModule.lazy_import, which enables the following new idiom for creating lazy imports that are visible to static checkers:

LibBraiding = PythonModule('sage.libs.braiding', spkg='libbraiding')
rightnormalform = LibBraiding.lazy_import(
  'rightnormalform', namespace=None)
centralizer,  supersummitset = LibBraiding.lazy_import(
  ('centralizer', 'supersummitset'), namespace=None)
