# The problems I attempt to solve
- `RepositoryKey.created_at` is available on the Github API, but not in
PyGithub
- `RepositoryKey.edit()` is not supported anymore by the Github API,
see https://developer.github.com/v3/repos/keys/#edit-a-deploy-key
# How I went about solving the problem
I added myself a new deploy key to one of my repositories, and recorded
the existing tests using my account.
I could not keep the existing test data as the specified key does not
exist anymore, I added a comment for the next contributor to help him
figure out how to record new tests.
This is a minor thing. It’s a convention, not a rule (obviously)—but it’s also a best practice.
Many text editors look for this kind of comment as the first line—or second line, if there is a shebang (the `#!/usr/bin/env python`, or whatever else)—and make use of this to determine the file’s encoding.
