* Fix a statement about coupling and cohesion that is not always true https://enterprisecraftsmanship.com/posts/cohesion-coupling-difference/#_types_of_code_from_a_cohesion_and_coupling_perspective * Fix a typing issue in an example `ApiClient` expects timeout to be an integer (based on a type hint), but `os.getenv` returns a string when `TIMEOUT` is set. * Specify the `None` return type where it is missed * Fix typing issues in some other places * Edit a statement about coupling and cohesion Co-authored-by: Roman Mogylatov <rmogilatov@gmail.com> Co-authored-by: Roman Mogylatov <rmogilatov@gmail.com>
